For the following circuit assume V = 1.5V, R = 10k, and R = R3 = 6kN VA Ra (a) Find R such that Vx = -2.5V assuming an ideal Op Amp and V = 1V, and Vc = 3V 48k, and VB = VC = OV = For the following questions assume R [15 pts] (b) Find Vx if the Op Amp has an Offset Voltage 15mV assuming an ideal Op Amp otherwise. [15 pts] (c) Find the closed loop transfer function Ay(s) = Vx(s)/VA(s) assuming an Op Amp with a UGBW of 5MHz and an open loop gain of 112dB. Hint: Sketch the Bode plot of the transfer function.
