A power-on reset circuit for use in an integrated circuit. The power-on reset circuit comprises an inverter, a switch means, and a number of diode-connected transistors. The switch means having a control terminal connected to an output terminal of the inverter is coupled between a power supply and an input terminal of the inverter. The diode-connected transistors are connected in series between the power supply and the input terminal of the inverter. The power-on reset circuit also comprises another diode-connected transistor connected between the input terminal of the inverter and a circuit ground. This diode-connected transistor is preferably connected in inverse series with the remaining diode-connected transistors.
