Abstract
The objective is to provide a delay circuit and an electronic circuit including a delay circuit which are capable of changing the operation speed of a circuit system including an operational amplifier and the delay circuit with ease. An electronic circuit includes a voltage generation circuit which generates a bias voltage, an operational amplifier which operates with a constant voltage and receives the bias voltage from the voltage generation circuit, and a delay circuit which operates with the constant voltage and receives the bias voltage from the voltage generation circuit so as to reduce fluctuations of current flowing in the delay circuit by the bias voltage.
