Question:

In the switched-capacitor circuit in Figure 15.12(a), the voltages are \(V_{1}=2 \mathrm{~V}\) and \(V_{2}=1 \mathrm{~V}\), the capacitor value is \(C=10 \mathrm{pF}\), and the clock frequency is \(f_{C}=100 \mathrm{kHz}\).

(a) Determine the charge transferred from \(V_{1}\) to \(V_{2}\) during each clock pulse.

(b) What is the average current that source \(V_{1}\) supplies?

(c) If the "on" resistance of each MOSFET is \(1000 \Omega\), determine the time required to transfer 99 percent of the charge during each half-clock period.
