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.

Section J6: FET Amplifiers & Amplifier Analysis Just as there were four basic configurations for a single stage BJT amplifier (CE, ER, CC, and CB), there are four basic configurations for a single stage FET amplifier. With respect to the figure to the right (a modified version of Figure 6.31 in your text), these configurations may

The indicated FET is a low-cost and easily available device. Voltage gain of the amplifier is 10. The optimum input-signal amplitude just before output-signal peak clipping is around 0.7 volt rms, and the equivalent output-voltage amplitude is 7 volt rms. At 100 % working specs, the circuit pulls 0.7 mA through the 12-volt DC supply.

Voltage Gain of Single stage Transistor Amplifier. The voltage gain of a single stage transistor amplifier is the ratio of a.c. output voltage to a.c. input signal voltage. Hence, in order to determine the voltage gain, you should consider only the a.c. currents and voltages in the circuit. In other words you have to consider the a.c. equivalent circuit of the transistor amplifier.
