This will happen during rising and falling edges of the input signal.sivakumar_tumma said:engrbabarmansoor said:what is short circuit current in a CMOS inverter?
The pulse to the inverter is not ideal square wave . there will be some rise and fall times.
similarly there will dealy in the response of NMOS and PMOS.
Because of these, there will be chance of ,for sometime, both the NMOS and PMOS will be on, shorting the Vdd to the ground. Since the impednace is less, there will large current passing through the inverter.
This current is called shortcircuit current.
