Consider the basic BiCMOS inverter in Figure 17.36 (a) in the text. Assume circuit and transistor parameters of \(V_{D D}=5 \mathrm{~V}\), \(K_{n}=K_{p}=0.1 \mathrm{~mA} / \mathrm{V}^{2}, V_{T N}=+0.8 \mathrm{~V}, V_{T P}=-0.8 \mathrm{~V}\), and \(\beta=50\).

(a) For \(v_{I}=2.5 \mathrm{~V}\), determine the current in each transistor.

(b) If the current calculated for \(Q_{1}\) were charging a \(15 \mathrm{pF}\) load capacitance, how long would it take to charge the capacitance from 0 to \(5 \mathrm{~V}\)?

(c) Repeat part (b) for the current in the transistor \(M_{P}\).
