< 6 Class B Output Stage Calculators

Load Resistance of Class B Stage

Go Load Resistance of Class B = (2*Peak Amplitude Voltage*Supply Voltage)/(pi*Supply Power)

Efficiency of Class B Output Stage

Go Efficiency of Class B = pi/4*(Peak Amplitude Voltage/Supply Voltage)

Negative Half of Maximum Power Dissipation in Class B Stage

Go Negative Maximum Power Dissipation = Supply Voltage^2/(pi^2*Load Resistance)

Maximum Power Dissipation in Class B Stage

Go Maximum Power Dissipation = (2*Supply Voltage^2)/(pi^2*Load Resistance)

Maximum Average Power from Class B Output Stage

Go Maximum Power in Class B = 1/2*(Supply Voltage^2/Load Resistance)

Efficiency of Class A

Go Efficiency of Class A = 1/2*(Output Voltage/Drain Voltage)

Efficiency of Class A Formula

Efficiency of Class A = 1/2*(Output Voltage/Drain Voltage)
η = 1/2*(V_out/V_drain)

What is a Class B amplifier?

Class B amplifier is a type of power amplifier where the active device (transistor) conducts only for the one-half cycle of the input signal. Since the active device is switched off for half the input cycle, the active device dissipates less power and hence the efficiency is improved.
