Differential Amplifier Circuit Using Mosfet. 10 watts mosfet amplifier notes. A bipolar junction transistor differential amplifier 11 1 1 dc characteristics using kirchhoff s voltage law the voltage at emitter v e1 and v e2 of the amplifier is v in1 v be1 v in2 v be2 from the theory of semiconductor physics.
Capacitors c3 c4 c5 must be rated 50v and c2 can be 10v. A bipolar junction transistor differential amplifier 11 1 1 dc characteristics using kirchhoff s voltage law the voltage at emitter v e1 and v e2 of the amplifier is v in1 v be1 v in2 v be2 from the theory of semiconductor physics. Simulate this circuit schematic created using circuitlab.
Vid vi1 vi2 common input.
Do not expect much performance from this amplifier. I d kvov 2 without the 2. Vod vo1 vo2 common output. The latter are used as input stages in op amps video amplifiers high speed comparators and many other analog based circuits.
