EXTENDED RANGE RMS-DC CONVERTER

Described herein is technology for, among other things, reducing offset errors in RMS-to-DC converters. The technology involves generating first and second feedback signals with first and second feedback paths respectively. A multiplier is then employed to receive first and second signals and provide a third signal based on multiplying the first signal and the second signal. The first signal is based on an input signal and the first feedback signal, and the second signal is based on the input signal and the second feedback signal. A chopper is then employed to receive an output signal, which is based on the third signal, and a chopping signal, and in turn provide a fourth signal based on multiplying the output signal with the chopping signal. As a consequence, the fourth signal represents the output signal shifted to a frequency different than that of low-frequency noise components of the first and second signals.
