Consider the MC14573 op-amp in Figure 13.14. The dc bias currents and small-signal voltage gains were determined in Examples 13.8 and 13.9. Redesign the circuit such that the width-to-length ratio of \(M_{1}\) and \(M_{2}\) is increased from 12.5 to 50 . All other circuit and transistor parameters remain the same.

(a) Determine the original transconductance of \(M_{1}\) and \(M_{2}\), and the new transconductance value.

(b) Determine the new values of voltage gain for the input and second stages, and the overall voltage gain.

Determine the dc bias currents in the MC14573 op-amp. Assume transistor parameters of |V| = 0.5 V (all transistors), k = 100 A/V, k = 40 A/V, and circuit parameters of V+ = 5 V, V = 5 V, and Rset = 225 ks2. Assume transistor width-to-length ratios of 6.25 for M3 and M4, and 12.5 for all other transistors.
