When a CMOS inverter output changes from 0 to 1 and then to 0, it returns to its initial state with energy consumed.
When a CMOS inverter output changes from 0 to 1 and then to 0, it returns to its initial state with energy consumed. Assume the inverter has an effective load capacitance C and the supply voltage is VDD.
a) Draw an equivalent circuit (with only R and C) when the output changes from 0 to 1.
b) Draw an equivalent circuit (with only R and C) when the output changes from 1 to 0.
