摘要： In a method and apparatus for generating a power supply voltage, an integrated circuit including an adaptive power supply voltage circuit is provided where a target signal is generated representing an ideal or approximated ideal performance characteristic of a functional block operating with the power supply voltage. A generated functional block test signal is generated representing the performance characteristic of the functional block under these conditions. The adaptive power supply voltage circuit compares the target signal with the generated functional block test signal and adjusts the power supply voltage continuously until the target signal and generated functional block test signal are substantially equal. When the target signal and generated functional block test signal are substantially equal, the power supply voltage is locked for subsequent use. By optimizing the power supply voltage, minimal power dissipation is provided.

摘要： The present disclosure relates to a differential signaling circuit including differential signaling circuitry having at least one output and one input, that can operate in multiple mode of operations while using a single, low voltage supply source. Two or more switches are included and configured to selectively couple a supply voltage to the output dependent on a mode of operation of the differential signaling circuitry. The circuit also includes a switch control biasing circuit operatively coupled to at least one of the switches and to the output of the differential signaling circuitry. The switch control biasing circuit provides a switch control biasing voltage to control a state of the switch based on a voltage level of the output. Further, a bulk biasing circuit is included and operatively coupled to the switch. The bulk biasing circuit selectively provides a bulk biasing voltage to the switch based on the voltage level of the output.

摘要： A multiphase clock generating circuit includes a multiphase clock generator that produces a plurality of multiphase output signals at a first frequency and a multiphase divider with delayed reset control. The multiphase divider with delayed reset control is operatively coupled to receive the plurality of multiphase output signals at the first frequency and further operative to produce a plurality of multiphase output signals at a second frequency based on reset control information. As a result, an interface can be supplied with and switch between multiphase clock at different frequencies within a short amount of time with reduced power consumption and circuit area.
