  • Circuits and methods for dynamic voltage management
    Patent number: 8773086
    Abstract: In one embodiment the present invention includes a circuit comprising a voltage adjust circuit and an input terminal of an electronic system. The voltage adjust circuit is coupled to receive an input voltage. The input terminal of the electronic system is coupled to receive a supply voltage from an output terminal of the voltage adjust circuit. The voltage adjust circuit makes an adjustment to the supply voltage based on a minimum voltage requirement of the electronic system. Accordingly, the leakage current supplied to the electronic system reduces, thereby saving power.

  • Power-on-reset circuit
    Patent number: 6198318
    Abstract: An apparatus is used to control a reset function of an electronic device. The apparatus includes a circuit adapted to monitor a system voltage level and deliver a control signal in response to the system voltage level falling below a first preselected value. A duration controller receives the control signal and delivers a first reset signal for a preselected duration of time after receiving the control signal. A voltage level controller receives the first reset signal, and delivers a second reset signal that persists until the system voltage rises above a second preselected magnitude.
