Consider the ac equivalent circuit of a CMOS common-source amplifier shown in Figure P4.62. The parameters of the NMOS and PMOS transistors are the same as given in Problem 4.61. Determine the small-signal voltage gain.

Data From Problem 4.61:-

The ac equivalent circuit of a CMOS common-source amplifier is shown in Figure P4.61. The transistor parameters for \(M_{1}\) are \(V_{T N}=0.5 \mathrm{~V}, k_{n}^{\prime}=\) \(85 \mu \mathrm{A} / \mathrm{V}^{2},(W / L)_{1}=50\), and \(\lambda=0.05 \mathrm{~V}^{-1}\), and for \(M_{2}\) and \(M_{3}\) are

\(V_{T P}=-0.5 \mathrm{~V}, \quad k_{p}^{\prime}=40 \mu \mathrm{A} / \mathrm{V}^{2}, \quad(W / L)_{2,3}=50, \quad\) and \(\lambda=0.075 \mathrm{~V}^{-1}\). Determine the small-signal voltage gain.
