ABSTRACT:
A multiple supply voltage device includes an input/output (I/O) network operative at a first supply voltage, a core network coupled to the I/O network and operative at a second supply voltage, and a power-on-control (POC) network coupled to the I/O network and the core network. The POC network is configured to transmit a POC signal to the I/O network and includes an adjustable current power up/down detector configured to detect a power state of the core network. The POC network also includes processing circuitry coupled to the adjustable current power up/down detector and configured to process the power state into the POC signal, and one or more feedback circuits. For reducing the leakage current while also improving the power-up/down detection speed, the feedback circuit(s) are coupled to the adjustable current power up/down detector and configured to provide feedback signals to adjust a current capacity of the adjustable current power up/down detector.
