Abstract
A DC voltage is synthesized from a combination of a plurality of N phases of an oscillator signal. A diode circuit is used to combine the N phases, and a relationship between components of the circuit is established to eliminate the Nth harmonic of the oscillator signal from the synthesized DC voltage. Provision of non-zero input series resistances for four diodes together with a non-zero summing output resistance therefor provides a DC voltage having no harmonics below the eighth harmonic for a double-integrating oscillator providing four equally displaced phases of a signal.
