Assignee: LATTICE SEMICONDUCTOR CORPORATION
Field: Basic communication processes (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 11:
12. A method comprising:
detecting a first supply voltage ramp traversal across a first threshold ramp voltage based, at least in part, on a ramp voltage generated by a ramp voltage selector based, at least in part, on a supply voltage provided by a power supply and monitored by the ramp voltage selector;
detecting a second supply voltage ramp traversal across a second threshold ramp voltage, wherein the second threshold ramp voltage is higher than the first threshold ramp voltage and the first and second threshold ramp voltages are lower than a nominal operating voltage associated with the power supply and/or the supply voltage;
determining a time at which to generate a POR signal based, at least in part, on an amount of time between the first supply voltage ramp traversal and the second supply voltage ramp traversal; and
generating the POR signal based on the determined time.
