Abstract: A device includes a voltage converter and an analog to digital converter (ADC). The voltage converter includes an input to receive a first voltage and an output to output a second voltage based on a switching signal having a first discrete converter frequency and a second discrete converter frequency. The ADC is coupled to and proximate to the voltage converter. The ADC includes a digital filter configured to substantially attenuate a first filter frequency and a second filter frequency. The voltage converter further includes a frequency control device configured to set the first discrete converter frequency and the second discrete converter frequency so that the first discrete converter frequency is approximately equal to the first filter frequency and the second discrete converter frequency is approximately equal to the second filter frequency.

Abstract: A driver includes a low-resistance charging path between a supply voltage rail and a first output node, a high-resistance charging path between the supply voltage rail and the first output node, an inverter coupled to the first output node and configured to enable and disable the low-resistance charging path, and a high-resistance discharging path between the first output node and a second output node. The first output node is coupled to a control terminal of a pass gate transistor in some implementations. The low-resistance charging path charges a voltage on the first output node to a threshold voltage of the pass gate transistor, and the high-resistance charging path charges the voltage on the first output node greater than the threshold voltage of the pass gate transistor. The high-resistance discharging path discharges the voltage on the first output node.

Abstract: A ripple voltage detector circuit comprises a pulse generator, a direct current-to-direct current (DC-DC) converter coupled to the pulse generator, and a first control loop coupled to the pulse generator and the DC-DC converter. The first control loop is configured to measure an output voltage of the DC-DC converter, determine an output ripple voltage of the output voltage, determine a ripple coefficient based on the output ripple voltage, determine a reference peak inductor current based on the ripple coefficient, and determine a peak value of an inductor current during a switching cycle, and transition a switching state of the DC-DC converter based on the reference peak inductor current and the peak value of the inductor current.

Abstract: A system includes a digital controller in a voltage regulator. The system also includes a passgate array including two or more passgate transistors, where the passgate array is configured to provide a load current to a load, and where the digital controller is configured to activate and deactivate each passgate transistor in the passgate array. The system also includes a feedback loop configured to provide an error signal to the digital controller, the error signal based on a difference between an output voltage of the voltage regulator and a programmed voltage for the voltage regulator. The digital controller is configured to activate or deactivate a passgate transistor based at least in part on the error signal. The digital controller is also configured to activate at least one passgate transistor and deactivate at least one passgate transistor responsive to a clock cycle.
