Abstract
Disclosed is a compensation circuit for compensating a change in timing information of an input signal caused by thermal variations in a first circuit. The first circuit comprises one or more devices each having a temperature dependent on the input signal. Accordingly, the compensation circuit comprises one or more compensation devices each having a temperature dependent on the input signal. The compensation circuit is connected in series with the first circuit and the series connection receives the input signal and provides a timing-compensated output signal with substantially the same timing information as of the input signal. The thermal characteristic of at least one of the one or more compensation devices is proportional or in some other known relation to a corresponding one of the one or more devices of the first circuit. The compensation circuit provides a compensation output signal having substantially opposite or inverse thermal distortions than the first circuit.
