Amplifier Circuits Introduction to Impedance and Bandwidth Control. Modified Response Curves Previous modules have concentrated on producing a flat frequency response over the required audio frequency range. It is sometimes necessary however, to modify the flat response of an audio amplifier by making particular stages of the amplifier frequency

The amplifier uses two 2N3823 FETs (Q1, Q2) and delivers an overall open-circuit gain of 400: The maximum i-f input is 2.5 mV rms before peak clipping takes place in the 1-V rms output. The selectivity of the circuit follows very nearly to that of the filter alone. For example, -3 dB at 2-kHz bandwidth to -40 dB at 160-kHz bandwidth.

Operational amplifiers have a basic task. They take an input potential (voltage) and produce an output potential that’s tens, hundreds, or thousands of times the magnitude of the input potential. In an amplifier circuit, the LM386 takes an audio input signal and increases its potential anywhere from 20 to 200 times.

It simply amplifies the input signal and produces gain according to the equation (1). Gain = [ ( R1 || R2)/ (rs+ R1 || R2 ) ] * (-gm) * ( rd || RD || RL) (1) Here, R1 and R2 are the input resistances, rs is the source resistance, RD is the resistance between bias …
