Hello, I've been working on a Multistage amplifier circuit for the past couple days and I cant seem to get it working correctly. The specs that I need to design for are:
a. Input impedance = 200 kΩ
b. Output impedance = 200 Ω
c. AC voltage gain = 300
d. Low frequency -3 dB point = 50 Hz
e. High frequency -3 dB point = 100 kHz
f. Output voltage swing = 6 V peak-to-peak without distortion
The output load resistor is 1 kΩ. The dc power supply is no higher than 20 V. There should be no operational amplifier in the circuit.
I've attached my schematic, as well as the output and frequency response for my circuit.
My capacitor values are off because my high and low frequency cutoffs aren't showing up, but I'm not sure which equations and values I should use to fix it.
My main request is if anyone has time, would you glance over the circuit and see if it looks like it would work and makes sense. If not, tell me which part i should mess around with more.
Thank you
