Question

(a) [P.C] Assuming the bandwidth of the readout circuit is limited by the non-inverting

amplifier stage (the last stage) and R4 = 1KN and R; = 280KN, estimate the

bandwidth of the readout circuit assuming that the internal compensation capacitor

creates the dominant pole in the frequency response of the op-amps?

(b) [P, C] With Vin= V₂cos(t) and V₁=1V and assuming Vpzr = 0.005 Vin, will there be

a frequency at which the output (V.) will be distorted? If so, what is that frequency?

(c) [D] With Vin= V₂cos(2*900t) and assuming R, = 0.5MQ, R4 = 1KQ, R; = 280KN,

R₁-1KQ, R₂=1KQ, C₁ = C₂ = CpzT= 10nf, what is the constrain on the V₁ if the

output is to be undistorted?
