Abstract
A power-on reset circuit includes a complementary-to-absolute-temperature circuit that outputs one control voltage, and a proportional-to-absolute-temperature (PTAT) circuit that outputs a PTAT current. The power-on reset circuit further includes various resistors that are coupled in series, and generate another control voltage based on the PTAT current that is outputted by the PTAT circuit. Further, the power-on reset circuit includes a comparator that compares the two control voltages to generate a power-on reset signal. The power-on reset signal is activated when a supply voltage is greater than or equal to a trip voltage, and deactivated when the supply voltage is less than the trip voltage. A functional circuit is configured to execute a reset operation associated therewith when the power-on reset signal transitions from a deactivated state to an activated state.
