The no-load voltage gain of the amplifier used in the circuit in the picture is
K = 2000, input resistance R1 = 50K and output resistance Ro = 500ohm.a) Calculate the voltage gain of the circuit Vo / Vg.b) Calculate the value of the capacitors C1 and C2, considering that the lower cut-off frequency of the circuit is 20Hz and the asymptote slope is desired to be 40db / decade.c) Calculate the upper cut-off frequency of the circuit.
A cascade amplifier is to be designed to meet these specifications:
Aυ = 5000 Rin ≥ 10 MΩ Rout ≤ 0.1 Ω How many amplifier stages will be required if the stages must use an op amp below? Because of bandwidth requirements, assume that no individual stage can have a gain greater than 50.
Op amp specifications: A = 85 dB Rid = 1 MΩ Ro = 100 Ω Ric ≥ 1 GΩ
