Classification: H03F,H03K

Abstract:
A compensation circuit for compensating for a change in timing information of an input signal caused by thermal variations in a first circuit;said first circuit comprising one or more devices each having an individual temperature dependent on said input signal,said compensation circuit comprising one or more compensation devices each having an individual temperature dependent on said input signal, andsaid compensation circuit being connected in series with said first circuit to form a second circuit, said second circuit receiving said input signal and providing a timing-compensated output signal with substantially the same timing information as said input signal; whereby:a thermal characteristic of at least one of said one or more compensation devices is one of proportional or a known relation to a corresponding one of said one or more devices of the first circuit, andsaid compensation circuit provides a compensation output signal having substantially opposite thermal distortions than said first circuit.
