WebDec 29, 2024 · Static power consumption is that when the CMOS gate is not switching, i.e. in a steady state when all inputs are held at some valid logic level and the circuit is not in charging states. Static power consumption is low and results from leakage current. In contrast, dynamic power consumption arises when the CMOS gate changes state.
