Abstract:
1. A delay element, comprising a delay generating part which generates an output signal by adding a specific delay amount to an input signal, and a delay control part for controlling the delay amount, wherein: the delay control part includes a delay adjusting circuit for adjusting the delay amount and a temperature compensating circuit for compensating a property change caused due to a temperature, the delay control part outputs a second control signal to control the delay amount, the delay adjusting circuit and the temperature compensating circuit are voltage-current conversion elements such that the delay amount is adjusted by a first control signal applied to the delay adjusting circuit from an external circuit and the property change is compensated by a voltage applied to the temperature compensating circuit, and the delay adjusting circuit and the temperature compensating circuit are connected in series such that current output from the temperature adjusting circuit is effected by the first control signal applied to the delay adjusting circuit and current output from the delay adjusting circuit is effected by the voltage applied to the temperature compensating circuit, and such that an effect of adjusting the delay amount by the delay adjusting circuit and an effect of compensating the property change by the temperature compensating circuit are synthesized to generate the second control signal.
