Abstract: An on-die voltage regulator having a suspend mode voltage generator and an active mode voltage generator. Output drivers of the active mode voltage generator are disabled in stages to reduce voltage droop when transitioning between the active mode voltage generator and the suspend mode voltage generator.

Abstract: Method and apparatus for analog compensation of driver output signal slew rate against device impedance variation. The method includes a signal termination device coupled to a driver output pad. In one embodiment, driver includes a pull-up circuit having at least one pull-up device and a pull-down circuit including at least one pull-down device. In one embodiment, the pull-up circuit and the pull-down circuit including corresponding pull-up and pull-down compensation resistive elements. Accordingly, the pull-up and pull-down compensation resistive elements provide analog compensation of a driver output signal slew rate against device impedance variation. In one embodiment, a slew rate of the driver output signal is within a predetermined slew rate range to avoid uncontrolled fast switching as well as unnecessarily slow switching in the driver output signal. Other embodiments are described and claimed.

Abstract: A method and apparatus for analog compensation of driver output signal slew rate against device impedance variation is described. The method includes a signal termination device coupled to a driver output pad. The driver includes a plurality of pull-up devices where each pull-up device is coupled between a driver supply voltage and the signal termination device. In addition, corresponding pull-down devices are coupled between a driver ground and the signal termination device. The driver includes pull-up and pull-down compensation resistive elements coupled in series between selected pull-down/pull-up devices and the signal termination device. Accordingly, the pull-up and pull-down compensation resistive elements provide analog compensation of a driver output signal slew rate against device impedance variation. Also, a slew rate of the driver output signal is within a predetermined slew rate range in order to avoid uncontrolled fast switching as well as unnecessarily slow switching in the driver output signal.
