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

Claim 0:
1. An adaptive power on reset (POR) signal generator, comprising:
a ramp voltage selector configured to monitor a supply voltage provided by a power supply and generate a ramp voltage based, at least in part, on the monitored supply voltage; and
a logic device configured to:
detect a first supply voltage ramp traversal across a first threshold ramp voltage based, at least in part, on the ramp voltage provided by the ramp voltage selector;
detect 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;
determine 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
generate the POR signal based on the determined time.
