1. Fig. 1 shows an initial approach for instrumentation amplifier. (a) Find an expression for output voltage vo. (5%) (b) Let all resistors be WAR. Give the common mode gain for the worst c*. (5%) (c) Remove the connection between node X and ground, recalculate the fommon mode gain. Compare the results of (b) and (c), and give an explanation briefly. (5%) Fig. 1 2. Fig. 2 shows a noninverting amplifier. It is fed with a sine-wave signal of peak voltage V, and is connected to a load resistor RL. The OP amp is specified to have output saturation voltages of kl3V and output current limits o f f 20mA. The unity-gain bandwidth and slew rate are ft = 2MHz and SR = 1VIps. (a) For RL = 1kR and f = lOkHz, what is the highest value of V, for which an undist rn slne wave output is obtained? (5%) (b) For the V, you found in (a), what is the highest frequency for the input signal without output distortion? (5%) Fig. 2
