Abstract

A power on reset circuit includes a first inverting circuit, a second inverting circuit, a charging apparatus, an output buffer, a current drainer, and a first capacitor. The first inverting circuit and the second inverting circuit are coupled between a voltage detection end and a signal control end in opposite directions. The current drainer drains a current from the voltage detection end according to a power voltage and a voltage on the signal control end. The charging apparatus charges the voltage detection end according to the voltage on the signal control end. The output buffer generates a reset signal according to the voltage on the signal control end.
