摘要： A phase interpolator for a CDR circuit produces an output clock having level transitions between the level transitions on two input clocks. The input clocks drive cross-coupled differential amplifiers with an output that can be varied in phase by variable current throttling or steering, according to an input control value. The differential amplifiers produce an output signal with a transition spanning a time between the start of a transition on the leading input clock up to the end of the transition on the lagging input clock. The output clock is linear so long as the transitions on the two input clocks overlap. Active integrators each having an amplifier with a series resistance and capacitive feedback path are coupled to each input to the cross-coupled differential amplifiers, which enhances overlap of the input clock rise times and improves the linearity of the interpolated output signal.

摘要： A method of operating a voltage regulator circuit includes generating a control signal by an amplifier of the voltage regulator circuit. The control signal is generated based on a reference signal at an inverting input of the amplifier and a feedback signal at a non-inverting input of the amplifier. A driving current flowing toward an output node of the voltage regulator circuit is generated by a driver responsive to the control signal, and the driver is coupled between a first power node and the output node. The feedback signal is generated responsive to a voltage level at the output node. A transistor, coupled between the output node and a second power node, is caused to operate in saturation mode during a period while the voltage regulator circuit is operating.
