摘要： Power control is facilitated. In accordance with one or more embodiments, power is supplied to power rails of an integrated circuit using a power control circuit including a power regulator and a reset circuit that is responsive to a supply voltage. The power regulator provides power to the power rails, based upon a control signal. The reset circuit controls the power regulator to provide power to the power rails independently of the control signal when the supply voltage is below an operational voltage level, and controls the power regulator to provide power to the power rails in response to the control signal when the supply voltage reaches the operational voltage level.

摘要： A method for generating a reference voltage includes generating a proportional-to-absolute temperature (PTAT) voltage across a first pseudo resistor. The first pseudo resistor includes a transistor. The method also includes converting the PTAT voltage to a current based on a resistance of the first pseudo resistor. The method also includes mirroring the current using a current mirror circuit and converting the mirrored current to a converted PTAT voltage using a second pseudo resistor. The second pseudo resistor includes a transistor. The first pseudo resistor and the second pseudo resistor include equal transistor types. The method also includes generating a complementary-to-absolute temperature (CTAT) voltage, and summing the converted PTAT voltage and the CTAT voltage to produce the reference voltage. The resulting reference voltage is temperature independent.

摘要： Methods, devices and circuits are provided for power-on-reset circuits with low static power consumption. One such circuit includes a detector that draws current from a supply voltage. The detector detects that the supply voltage has exceeded a trip-point voltage level and then disables current draw from the detector. The detector responds to an enable signal by enabling current draw from the detector. A pulse generator generates a reset signal in response the supply voltage transitioning from a voltage below the trip point voltage level to above the trip point voltage level. A monitor detects that the supply voltage has dropped and provides, in response thereto, the enable signal to the detector to enable current draw from the portion of the detector.
