Abstract
We propose a compact power-on reset circuit consisting of a switched capacitor, a capacitor, and a Schmitt trigger inverter. A switched capacitor working with a clock signal charges the capacitor. Thus, the voltage across the capacitor is increased toward the supply voltage. The circuit provides a reset pulse until the voltage across the capacitor reaches the high threshold voltage of the Schmitt trigger inverter. The proposed circuit is simple, compact, has no static power consumption, and works for a wide range of power-on rising times. Furthermore, the clock signal is available while the reset pulse is activated. The proposed circuit works for up to 6 s of power-on rising time, and occupies a 60 x 30 mu m(2) active area.
