Abstract: Mechanisms for providing linear relationship between temperatures and digital codes are disclosed. In one method, at a particular temperature, a circuit in the sensor provides a temperature dependent reference voltage, and a compared voltage, to a comparator. The temperature dependent reference voltage depends on temperature in complement to absolute temperature or alternatively depends on temperature in proportion to absolute temperature. The compared voltage is generated corresponding to digital analog converter (DAC) codes as inputs. Another circuit varies the DAC codes until the temperature dependent reference voltage and the compared voltage are equal so that the dependent reference voltage corresponds to a DAC code. The various temperatures experienced by the temperature sensing circuit and the DAC codes are substantially linearly related

Abstract: 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.

Abstract: 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.
