WebTo minimize the eEect of the short-circuit power dissipation it is desirable to have equal input and output edge times [42]. In this case, the power dissipation is less than 10% of the total dynamic power dissipation. The lealcage-current power dissipation is due to: 1. Reverse-bias diode leakage current. WebPower dissipation of a gate occurs in two ways: static power dissipation and dynamic power dissipation. Glitch power comes under dynamic dissipation in the circuit and is directly proportional to switching activity. Glitch power dissipation is 20%–70% of total power dissipation and hence glitching should be eliminated for low power design.
