| 摘要 |
A power-on reset ("POR") methodology and circuit for an electronic circuit using multiple supply voltage domains asserts a reset signal upon ramp up of the first supply voltage signal, maintains the reset signal until all of the supply voltage signals have ramped up, and de-asserts the reset signal after all of the supply voltage signals have ramped up. Practical embodiments of the POR circuit include a control circuit that reduces static and/or dynamic current leakage associated with the operation of the POR circuit.
