Consider Problem 12.62.

(a) What is the magnitude of the ideal transresistance transfer function \(\left|A_{z f}\right|\) as the transistor transconductance parameter \(g_{m} \rightarrow \infty\).

(b) Determine the value of \(g_{m}\) so that \(\left|A_{z f}\right|\) is within 95 percent of the ideal magnitude.

Data From Problem 12.62:-

The transistor parameters for the circuit shown in Figure P12.62 are \(V_{T N}=\) \(0.4 \mathrm{~V}, K_{n}=0.5 \mathrm{~mA} / \mathrm{V}^{2}\), and \(\lambda=0\).

(a) Find (i) the quiescent drain current \(I_{D Q}\) and (ii) the small-signal transistor parameters.

(b) Determine the transresistance transfer function \(A_{z f}=v_{o} / i_{s}\).

(c) Find the output resistance \(R_{o f}\).
