  • Method and apparatus for regulating output power of signal amplifier
    Patent number: 5381115
    Abstract: A method and apparatus for controlling the output power level of an amplifier that is highly insensitive to temperature variations. The method intentionally shuts down the amplifier for a very short period of time in order to reveal the detector diode's thermally induced error voltage. This voltage is then stored for a subsequent subtraction from the total detected voltage after the amplifier is turned back on. The detector diode is therefore compensated against itself to obtain a higher level of detection accuracy.
