Abstract
A delay circuit and an electronic system equipped with the delay circuit are provided. The delay circuit includes an input terminal, an output terminal, a bias current generator and a delay generator. The bias current generator is coupled between a first reference voltage and a second reference voltage, and is configured to generate a bias current. The delay generator is coupled between the first reference voltage and the second reference voltage, and is configured to generate a delay of the delay signal relative to the input signal according to the bias current. The bias current generator includes a current mirror, a current module and a transistor. The delay generator includes a first current mirror sub-circuit, a second current mirror sub-circuit, a transistor, a capacitor, a switch circuit and a Schmitt inverter, wherein the output terminal is coupled to the Schmitt inverter to output the delay signal.
