Analog divider circuitry

Claim 1

An analog divider network, comprising: a. an operational amplifier having an input terminal coupled to a first analog signal and an output terminal; b. a switching network; c. an electrical impedance serially coupled to the switching network, such electrical impedance and switching network being coupled between the input terminal and the output terminal; d. means, including a triangular waveform generator, and a comparator network having one input coupled to the triangular waveform generator and a second input fed by the analog signal and an output coupled to the switching network for actuating the switching network to periodically decouple the electrical impedance from the input terminal and the output terminal for a time duration inversely proportional to the magnitude of a second analog signal; e. a first variable electrical impedance means, coupled between the first analog signal and the input terminal of the operational amplifier, for changing the electrical impedance thereof in accordance with a control signal; f. a second variable electrical impedance means, similar to the first variable electrical impedance means, coupled between the second analog signal and the comparator network, for changing the electrical impedance thereof in accordance with the control signal; g. a reference voltage source; and h. means coupled to the reference voltage source and responsive to the second analog signal, for producing the control signal in accordance with the difference between the second analog signal and the reference voltage.
