ABSTRACT:
A voltage divider and inverter provide a power-on-reset signal. The divider is placed between high and low power voltages, the divided voltage is the input to the inverter and the output of the inverter is the power-on-reset signal. The divider and inverter may be implemented on a single integrated circuit and accompany other, control and operational, circuitry on the integrated circuit. The divider is chosen so that the input to the inverter reaches the inverter's threshold voltage when the power voltage reaches a predetermined value.
