ABSTRACT:
A low-voltage power amplifier system achieves high efficiency with a low power supply and a low input voltage. The low-voltage power amplifier system includes an enable input for switching the system between an ON state and an OFF state. The low-voltage power amplifier system can directly amplify the input signal and can achieve a frequency multiplication by an even factor. The low-voltage power amplifier system includes a biasing capacitor, a biasing resistor, a npn or pnp transistor, an output or resonant inductor, an output or resonant capacitor, and an optional stability resistor.
