ECEN 325 HOMEWORK # 3 ( Due date: Monday, September 22, 2008) 1. Sketch the magnitude and phase bode plot for the below transfer function: T(s) = (s +100)/[(s+1)(s+10,000)] 2. In the circuit below, the op-amp’s open-loop gain is A(s): (a) Derive the transfer function T(s) = V o (s)/V s (s) as a function of R 1 , R 2 , R 3 , R 4 and A(s) (b) Sketch |T(j ω )| dB : R 1 = R 3 = R 4 = 1 k Ω, R 2 = 9 k Ω , and A(s) = 10 5 /(1 + (s/ 2 π 5)) (c) If the slew rate is 0.5 V/ μ s, find the maximum amplitude of V s at the corner frequency

Unformatted text preview: before the output distorts (d) Verify your answers in parts (b) and (c) using UA741 op-amp in PSPICE 3. (a) For the circuit below, find the gain V o / V s in terms of resistors. Assume the op-amps are ideal. (b) For R 1 = R 2 =1 k , R 3 = 3 k , R 4 = 6 k , R 5 = 5 k , R 6 = 10 k , find the maximum amplitude of V s before the output distorts if V s (t) = A s sin (2 10 4 t) and slew rate of the op-amp is 0.5 V/ s....
