Power Conversion Efficiency of Class A - Power Conversion Efficiency of Class A is the ratio of the useful output power of a power conversion device to the input power of a class A output stage amplifier.
Peak Amplitude Voltage - (Measured in Volt) - Peak amplitude Voltage is the change between peak (highest amplitude value) and trough (lowest amplitude value, which can be negative) in an op amp.
Input Bias Current - (Measured in Ampere) - Input Bias Current is defined as the average of input current in the operational amplifier. It is denoted as IB.
Load Resistance - (Measured in Ohm) - Load Resistance is defined as the cumulative resistance of a circuit as seen by the voltage, current or power source driving that circuit.
Supply Voltage - (Measured in Volt) - Supply Voltage is also defined defined as the bias voltage applied to the op amp for Q2(transistor 2) pin. It is also defined as as voltage at collector.
