  • Patent number: 5012139
    Abstract: A full wave rectifier/averaging circuit for processing an input signal having a large dynamic range. A rectification circuit is responsive to the input signal for providing a first signal to a current mirror whereby the current mirror provides a second signal in response to the first signal. An averaging circuit is coupled to the current mirror to perform averaging of the second signal. An output circuit is coupled to the averaging circuit to provide an output signal at an output terminal.
