Power Conversion Efficiency of Class A Output Stage

Go Power Conversion Efficiency of Class A = 1/4*(Peak Amplitude Voltage^2/(Input Bias Current*Load Resistance*Supply Voltage))

Bias Current of Emitter Follower

Go Input Bias Current = modulus((-Supply Voltage)+Saturation Voltage 2)/Load Resistance

Power Output Capability Factor

Go Power Output Capability Factor = (Maximum Output Power)/(Peak Drain Voltage*Peak Drain Current)

Peak Output Voltage Value at Average Load Power

Go Peak Amplitude Voltage = sqrt(2*Load Resistance*Average Load Power)

Instantaneous Power Dissipation of Emitter-Follower

Go Instantaneous Power Dissipation = Collector to Emitter Voltage*Collector Current

Load Power of Output Stage

Go Load Power of Output Stage = Supply Power*Power Conversion Efficiency

Supply Power of Output Stage

Go Supply Power of Output Stage = 2*Supply Voltage*Input Bias Current

Saturation Voltage between Collector-Emitter at Transistor 1

Go Saturation Voltage 1 = Supply Voltage-Maximum Voltage

Saturation Voltage between Collector-Emitter at Transistor 2

Go Saturation Voltage 2 = Minimum Voltage+Supply Voltage

Load Voltage

Go Load Voltage = Input Voltage-Base Emitter Voltage

Drain Current of Class B Amplifier

Go Drain Current = 2*(Output Current/pi)

Drain Current of Class B Amplifier Formula

Drain Current = 2*(Output Current/pi)
I_d = 2*(I_out/pi)

What is class A output stage? Where are class A amplifiers used?

A Class A amplifier stage passes the same load current even when no input signal is applied so large heatsinks are needed for the output transistors. These types of devices are basically two transistors within a single package, one small “pilot” transistor and another larger “switching” transistor.

The Class A Amplifier more suitable for outdoor musical systems, since the transistor reproduces the entire audio waveform without ever cutting off. As a result, the sound is very clear and more linear, that is, it contains much lower levels of distortion.
