摘要

A delay circuit includes a MOSFET and bias voltage sources. The bias voltage sources apply a voltage difference between the drain and source of the MOSFET. The bias voltage source supplies a source voltage to a source electrode of the MOSFET. The bias voltage source supplies a drain voltage to a drain electrode of the MOSFET. An input signal to be delayed is propagated through the gate of the MOSFET in the gate width direction (y-axis direction).
