(a) Suppose a novel voltage buffer has been invented, which exhibits Ri > ` and Ro > 0, and accepts an input voltage vI to give the output voltage

Sketch and label vI (t) and vO(t) if vI (t) is a voltage source producing a triangular wave with peak values of 610 V. (b) To eliminate the effects of the nonlinearity stemming from the cubic term, let us interpose an op amp between the source vI and this buffer, in a manner similar to Assuming the op amp has a 5 `, sketch and label vI (t) and vO(t) as well as the op amp’s output vOA(t). (c) Find the gain a suffi cient to keep the output error down to 1 mV when vI (t) peaks out. Hence, sketch and label vE(t).
