  • Method super-regenerative transceiver, and computer system for providing short range communication with reduced current drain
    Patent number: 5621756
    Abstract: The current invention is a method (100), super-regenerative transceiver (300), and computer system (500) for providing short range communication with reduced current drain. A control unit provides an amplifier "ON" pulse periodically to a radio frequency amplifier to allow reduced current drain. The radio frequency amplifier eliminates antenna effects in an input signal to provide an amplified input signal. The control unit also provides a receiver "ON" pulse to a super-regenerative receiver immediately following the amplifier "ON" pulse to allow reduced current drain. The super-regenerative receiver detects received data given the amplified input signal.
