Hi,
I'm required to design a 3 stage multistage BJT amplifier with the following requirements.
stage 1: bjt differential pair with current mirror load and tail current
stage 2: bjt gain stage with an active load and current mirror bias
stage 3: bjt low output impedance stage
The amplifier can contain: frequency compensation capacitor, resistor for setting the bias reference current, potentiometer for offset voltage control. The amplifier is to be supplied by two DC supply voltages: VCC =+10V and VEE=-10 V.
The amplifier should have a minimum voltage gain of 2000 and an output resistance less than 100 ohms.
I've read on multistage amplifiers all day today and hasn't got a clue on how to approach this problem.
ANY kind of help or pointers or hints will be very much appreciated. Thank you!!
