Abstract
A delay circuit has: an inverting receiver with a resistive element, the inverting receiver having an input node for receiving an input signal and an output node coupled to the resistive element; a capacitive element, coupled to the output node of the inverting receiver and the resistive element; a first transistor, having lower turned ON voltage at higher temperature; a second transistor, used for generating a rail to rail signals on a terminal of the first transistor; and an output inverter, having an input node coupled to the first transistor and an output node for outputting an output signal of the delay circuit. Further, a third transistor is used for enhancing pulling low of the output signal of the delay circuit.
