Static Power in CMOS Solution

Follow our step by step solution on how to calculate Static Power in CMOS?

FIRST Step Consider the formula

P st = P t - P dyn

Next Step Substitute values of Variables

∴

P st = 113.5mW - 46.13mW

Next Step Convert Units

∴

P st = 0.1135W - 0.0461W

Next Step Prepare to Evaluate

∴

P st = 0.1135 - 0.0461

Next Step Evaluate

∴

P st = 0.06737W

LAST Step Convert to Output's Unit

∴

P st = 67.37mW

Variables

CMOS Static Power

CMOS Static Power is defined as the leakage current due to the very low static power consumption in CMOS devices.

Symbol: P_st

Measurement: PowerUnit: mW

Note: Value should be greater than 0.

Formulas to find CMOS Static Power

Total Power

Total Power is the total power inside CMOS Circuit.

Symbol: P_t

Measurement: PowerUnit: mW

Note: Value should be greater than 0.

Formulas to find Total Power

Dynamic Power

The Dynamic Power is calculated during the rise and fall of the input signal. These are smaller then the dynamic power dissipation.

Symbol: P_dyn

Measurement: PowerUnit: mW

Note: Value should be greater than 0.

Go Activity Factor

α = \frac{P s}{C \cdot {V bc}^{2} \cdot f}

Go Switching Power

P s = α \cdot (C \cdot {V bc}^{2} \cdot f)

Go Dynamic Power in CMOS

P dyn = P sc + P s

Go Short-Circuit Power in CMOS

P sc = P dyn - P s

How to Evaluate Static Power in CMOS?

Static Power in CMOS evaluator uses CMOS Static Power = Total Power-Dynamic Power to evaluate the CMOS Static Power, The Static Power in CMOS formula is calculated when the CMOS devices have very low static power consumption. This is the result of leakage current. CMOS Static Power is denoted by P_st symbol.

How to evaluate Static Power in CMOS using this online evaluator? To use this online evaluator for Static Power in CMOS, enter Total Power (P_t) & Dynamic Power (P_dyn) and hit the calculate button.
