sci.CMOS-inverter-power-dissipation Calculator
Calculates dynamic switching power P = α × C × V² × f and static leakage power of a CMOS gate from activity factor, capacitance, voltage, and frequency. Dynamic power scales quadratically with supply voltage — reducing Vdd from 1.2 V to 1.0 V cuts dynamic power by 31%.
Inputs
C Load Ff
Ability to store electric charge (F). Capacitors charge quickly and release energy fast. Common values: pF to μF.
Vdd V
Electric potential difference (V). Drives current through a circuit. Household: 120 V (US) or 230 V (EU/UK).
F Mhz
Cycles per second (Hz). Audible sound: 20 Hz – 20 kHz. Make sure units match what the formula expects.
Alpha Activity
A multiplier applied in the calculation.
Ileak Na
Rate of charge flow (A). I = V/R. Above ~100 mA through the body can be lethal. Fuses protect against overcurrent.
Results
dynamic power P_dyn (mW)
Sample size or count used in the calculation.
static leakage power P_static (μW)
The value at the specified point or condition.
total power (mW)
The combined total across all inputs and components.
P_dyn = α·CL·VDD²·f
Sample size or count used in the calculation.
energy per operation
The proportional relationship between two quantities.
scaling trend
The direction and rate of change in the data series.
