Abstract
A charge-coupled device (CCD) delay line having a temperature compensation circuit capable of compensating for temperature variations for providing an accurate and consistent delay of an input signal. The temperature compensation circuit includes first and second registers for transferring charges, and a sample-and-hold circuit connected between outputs of each register and two inputs of a differential amplifier. The differential amplifier supplies a signal which corresponds to temperature variations to properly bias the input signal.
