Power amplifier circuits (output stages) are classified as A, B, AB and C for analog designs—and class D and E for switching designs. The power amplifier classes are based on the proportion of each input cycle (conduction angle) during which an amplifying device passes current. . High Voltage, High Efficiency MOSFET RF High Voltage, High Efficiency MOSFET RF Amplifiers – series RLC circuit. The C is the specified Ciss from the data sheet at the desired operating supply voltage. The R is the effective series resistance, ESR,. Class-A Amplifier Signal. A class A power amplifier is defined as a power amplifier in which output current flows for the full-cycle (360 °) of the input signal. In other words, the transistor remains forward biased throughout the input cycle. Class-A Amplifier.
