Consider the CMOS inverter of fig 13.17 with Qn amd Qp matched and with the input Vi rising slowly from 0 to VDD. At what value of Vi does the current flowing through Qn and Qp reach its peak? Give an expression for the peak current, neglecting Lamba(n) and Lambda(p). For Kprime(n)=300ua/V^2, W/L(n)=1.5, VDD=1.8V and Vtn=.5V. Find the value of the peak current.
