Current Amplifier Circuit Using Mosfet. A current amplifier circuit is a circuit which amplifies the input current by a fixed factor and feeds it to the succeeding circuit. The photodiode absorbs energy from light and releases electrons thereby acting as an input current source.
However in power circuits it s a different story efficiency it s usually better. This circuit operates on the principle of multi stage power amplification consisting of pre amplifiers drivers and power amplification using mosfet. Audio amplifier circuit using mosfet transistor.
50 watts mosfet amplifier.
The circuit can be assembled on a vero board. This means that v g v d and thus v gd 0 v. Consider the above current mirror circuit using mosfet the mosfet transistor m1 is in the saturation region as the v ds v gs. As you can see the drain of q 1 is shorted to its gate.
