==POWER ON RESET (POR) CIRCUIT - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18311696 titled 'POWER ON RESET (POR) CIRCUIT

The patent application describes a power-on reset (POR) circuit that includes a delay circuit to control the timing of signals sent to logic circuits after receiving a power supply voltage.

* The delay circuit outputs a first signal to the logic circuits before a delay time, and a second signal after the delay time.
* Components of the delay circuit include a voltage drop device, a switching device with on-resistance, and a capacitance device.
* The on-resistance of the switching device and the capacitance of the capacitance device determine the delay time.
