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.
How to Calculate Condition of maximum power conversion efficiency?
Condition of maximum power conversion efficiency calculator uses supply_voltage = Input Bias Current*Load Resistance to calculate the Supply Voltage, The Condition of maximum power conversion efficiency formula is defined as attainable is 25%. Because this is a rather low figure, the class A output stage is rarely used in high-power applications (>1 W). Supply Voltage and is denoted by V_{i} symbol.
How to calculate Condition of maximum power conversion efficiency using this online calculator? To use this online calculator for Condition of maximum power conversion efficiency, enter Input Bias Current (I_{B}) and Load Resistance (R_{D}) and hit the calculate button. Here is how the Condition of maximum power conversion efficiency calculation can be explained with given input values -> 0.008 = 1E-05*800.
