To charge the left capacitor, the output buffer of the Pseudo-CMOS inverter consists of transistors with width of 2mm (W/L=100) and 6mm (W/L=300). The performance of the negative voltage generator strongly depends on the threshold voltage of the PMOS diode-connected transistors. To reduce the reverse leakage current, the gate width of each diode-connected transistor is smaller (W/L=50) than that of the inverter. The measured waveforms and output voltage versus the output current are shown in Figs. 18.1.4(b) and 18.1.4(c), respectively. The output voltage (VOUT) of the negative voltage generator is -1.6V in the case o
