The CMOS transmission gate shown in Fig. P10.3 has an input voltage of 2.5 V when it turns off. The W/L of the n-channel is 5 μm/0.8 μm and the W/L of the p-channel is 15 μm/0.8 μm. Assume the total parasitic capacitance between the output node and ground is 50 fF, VDD = 5 V, and that the clock signals change very fast. Also ignore changes due to overlap capacitance. Estimate the change in output voltage due to charge-injection. What will the final output voltage be?
