OPAMPS

Unit-1

1

Integrated Circuits Upto 1950 Vacuum Tubes were used.

Transistor was first invented in 1947 by 1.

William B. Shockley, 2. John Bardeen and 3.

Walter H. Brattain (refer below figure).

This was invented in BELL TELEPHONE Laboratories

2

Integrated Circuits (contd..,)

Further development has introduced the

Integrated Circuits (ICs).

This concept of ICs was introduced during

1960 by both Texas Instruments and Fairchild

Semiconductors .

3

Classification of ICs

Linear (Analog) ICs: These are connected todevices that collect signals from the environment orsend signals back to the environment.

Ex: a microphone converts fluctuating vocal sounds intoan electrical signal of varying voltage (Op-Amp).

Digital ICs: These are designed to accept onlyvoltages of specific given values. Circuit design withbinary quantities, on and off representing 1 and0.

Ex: Microcontroller and Microprocessors consistinglarge number of Digital Circuits.

4

Based on the above requirements two distinct

types of ICs had developed

1. Monolithic ICs: Derived from Greek monosmeans single and lithos means stone.

5

2. Hybrid or Multi-chip ICs: The activecomponents are diffused transistors or diodes. The

passive components may be group of diffused

resistors or capacitors on a single chip, or they may

be thin-film components.

Ex: Hybrids ICs are widely used for high power audio

amplifier applications from 5 W to more than 50 W.amplifier applications from 5 W to more than 50 W.

6

Drawbacks of Monolithic ICs

Low power rating (Max power rating

Based on their chip size ICs can be further classified as:

1. Small scale integration (SSI)3 to 30 gates/chip.(Logic gates, Fliip-flops)

2. Medium scale integration (MSI)30 to 300 gates/chip. (Counters, Multiplexers, Adders)

3. Large scale integration (LSI)300 to 3,000 gates/chip. (8-Bit Microprocessors, ROM, RAM)

4. Very large scale integration (VLSI)more than 3,000 gates/chip. (16 and 32 Bit Microprocessors)

Notice: The closed-loop gain Vo/Vin is

dependent upon the ratio of two

resistors, and is independent of the

open-loop gain. This is caused by the use

of feedback output voltage to subtract

from the input voltage.

Common Mode Rejection Ratio (CMRR): the

relative sensitivity of an op-amp to a

difference signal as compared to a common

22

Input offset current: The difference between the biascurrents at the input terminals of the op- amp is calledas input offset current.

Input offset voltage: A small voltage applied to the inputterminals to make the output voltage as zero when thetwo input terminals are grounded is called input offsetvoltage

Input bias current: Input bias current IB as the averageInput bias current: Input bias current IB as the averagevalue of the base currents entering into terminal of anop-amp

IB= IB+ + IB

Thermal Drift: Bias current, offset current and offsetvoltage change with temperature. A circuit carefullynulled at 25oc may not remain so when thetemperature rises to 35oc. This is called drift.

by applying negative pulse to this pin. To avoid anypossibility of false triggering this pin is to beconnected to +VCC.

To prevent possibility if miss triggering the

multivibrator on positive pulse edges, a wave

shaping circuit consisting of R, C2 and D is

connected between pin2 and pin8

Introduction

Evolution of PLL has began in early 1970s.

Due to its cost it has not preferred.

As there is rapid development in IC

technology, this PLL has emerged as one of

the fundamental building blocks in todays

Electronic technology.

Applications of PLL

Frequency Modulation(FM) stereo decoders

Motor speed controllers

Tracking filters

Frequency synthesized transmitters and receiversreceivers

FM demodulators

FSK decoders

Generation of local oscillator frequencies in TV and in FM tuners.

PLL ICs

SE/NE 560 series-

560, 561, 562, 564, 565, 567

For more economical operation, discrete ICs For more economical operation, discrete ICs

can be used to construct a PLL

Operating Principle of PLL

In short PLL goes through three states: free

running, capture and phase lock.

Some PLLs can also contain Amplifiers after

LPF.

Important definition in relation to PLL

Lock in range (%fo): once PLL is locked, it can

track incoming frequency. The range of

frequency where PLL can maintain lock with

input frequency is called Lock in range or

Tracking range.

Capture range (%fo): The range of frequencies Capture range (%fo): The range of frequencies

over which PLL can acquire lock with an input

signal is called Capture range.

Pull in time: The total time taken to establish

lock is called Pull in time

Pull in time depends on the initial phase and

frequency differences between the two signals

as well as on overall loop gain and loop filter

characteristics

Performance characteristics of DAC

Resolution: It is the reciprocal of maximumnumber of discrete steps in the output.

Ex: For n-bit DAC Resolution is given as

1x100/(2n-1).

Accuracy: It is a comparison of the actual outputof a DAC with the expected output.

Ex: Converter has full scale deflection of 10V andEx: Converter has full scale deflection of 10V andaccuracy is 0.1% then maximum error for anyoutput voltage is (10V)(0.001)=10mV.

Linearity: A linear error is a deviation from theideal straight-line output of a DAC.

Performance characteristics of DAC (contd.)

Monotonicity: A DAC is monotonic if it does

not miss any steps when it is sequenced over

its entire range of input bits.

Settling time: it is defined as the time it takes

a DAC to settle within 1/2 LSB of its final

value when a change occurs in the input code.

Analog to Digital converter

Concepts of ADC

Resolution:

An ADC translates a continuous analog signal

into a series of binary numbers.

The Resolution of an ADC can be expressed as The Resolution of an ADC can be expressed as

the number of bits used to represent each

value of the analog signal.

Ex: A 4-bit ADC can represent 16 different values

of analog signal.

Analog to Digital converter (Contd.)

Conversion time:

The conversion of a value on an analog waveforminto a digital quantity is not instantaneous event,but it is a process that takes a certain amount oftime (Refer figure in next slide).

Sampling theory: Sampling theory:

In ADC an analog waveform is sampled at a giventime and the sampled value is then converted to abinary number.

Ex: if ADC make one conversion in 1ms then 1000conversions can be made in ______.


[Note: Nyquist Rate: In order to represent the

analog waveform, the minimum sample rate

must be greater than twice the maximum

frequency component of analog signal. This

minimum sample rate is called as Nyquist rate.]


Quantization Error:

Quantization refers to determining a value for an

analog quantity.

An analog signal may change during conversion

time, its value at the end of conversion may not be

the same as it was at the beginning (unless it is DC).the same as it was at the beginning (unless it is DC).

This change in value of the analog signal during the

conversion time produces the error called as

Quantization Error.

Method to reduce the error is using sample and

hold circuit at input to the ADC.

Types of ADCsFlash ADC or Comparator type ADC

Requires 2n-1

comparators for

conversion to n-

bit binary code.

Advantage:

Provides fast

converting time.
