Abstract
A circuit for compensating the temperature dependence of gate propagation times includes a signal input for feeding-in an input signal; a signal output for issuing an output signal; a multiplexer having an output connected to the signal output and three inputs; a delay gate connected between one of the inputs of the multiplexer and the signal input, another of the inputs of the multiplexer being directly connected to the signal input; and a control input connected to a further one of the inputs of the multiplexer for controlling the multiplexer in dependence on temperature and feeding the input signal to the signal output delayed in a lower temperature range, undelayed in an upper temperature range and mixed, delayed as well as undelayed in a temperature range therebetween.
