Simple FET DC Amplifier. Figure 2.19 presents the circuit of a typical one-stage DC voltage amplifier comprising a 2N2608 FET (Q1). This stage occupies no load voltage gain of 5.65. Stages like these can be cascaded for higher gain but proper setups must be ensured for biasing the gate-source junction at each stage.

The next diagram below exhibits the circuit of a two-stage FET amplifier which involves a couple of similar RC-coupled stages, similar what was discussed in the above segment. This FET circuit is designed to provide a large boost (40 dB) to any modest AF signal, and could be applied both individually or introduced as a stage in equipment requiring this capability.

It is given as. gm = Delta (ID) / delta (VGS) (2) To produce the desired gain three potential divider biased circuits were cascaded in series and the total gain is the product of the gains of individual stages. Total Gain = A1*A2*A3 (3) Where, A1, A2 and A3 are the gains of first, second and third stage respectively.
