Abstract
A power-on reset (POR) circuit includes a first transistor and a stack of transistors. The first transistor generates an enable voltage based on a first supply voltage. The enable voltage is a reduced version of the first supply voltage and ramps up based on a ramp-up of the first supply voltage. The stack of transistors generates a control voltage. The control voltage is a reduced version of the enable voltage and ramps up based on the ramp-up of the enable voltage. The control voltage delays ramping of the enable voltage such that the enable voltage ramps up to a first threshold voltage associated with the stack of transistors in a first time period. Further, a reset signal generated by the POR circuit is asserted when the enable voltage exceeds the first threshold voltage at the end of the first time period.
