Abstract
The present invention relates to analog computation circuits that use a synchronous demodulator topology which can be configured to perform arithmetic computation, power measurements, and/or energy measurement of various analog signals. The computation circuits have circuitry that generates an output signal based on the values of a first input signal, a second input signal, and a reference signal. This invention provides accurate computation of two signals by using modulation circuitry (e.g., &Dgr;-&Sgr; modulation circuitry), demodulation circuitry (e.g., multiplying digital-to-analog converters), delay circuitry, and output circuitry.
