For a non-inverting Op Amp circuits shown below (R1=10KΩ, Rf = 100KΩ), calculate the expected closed-loop voltage gain and the input impedance.
a. Close Loop Gain:
b. Zin:
c. Vout:
d. V-:
(1) Apply an input voltage of 1 VDC to the circuit (as shown), calculate the voltage gain from the circuit (Vout/Vin):
(2) Apply a sinusoidal input voltage with 1V peak (f = 100Hz) as input voltage, calculate the voltage gain of the circuit (Vout_peak/Vin_peak); determine the phase relationship of the Vin and Vout:
