Abstract: Aspects of the technology described herein relate to an ultrasound device that may has a phase-locked loop (PLL) that includes a digitally-controlled oscillator (DCO). The DCO includes a plurality of current source unit cells with respective drain switches a plurality of current source unit cells with respective source switches. The plurality of current source unit cells with respective drain switches and the plurality of current source unit cells may have different circuit topologies. Switching on one of the plurality of current source unit cells with respective drain switches may cause a voltage transition at an internal node proceeding in one voltage direction and switching on one of the plurality of current source unit cells with respective source switches may cause a voltage transition at an internal node proceeding in the opposite voltage direction.

Abstract: Aspects of the technology described herein relate to control circuitry configured to turn on and off the ADC driver. In some embodiments, the control circuitry is configured to turn on and off the ADC driver in synchronization with sampling activity of an ADC, in particular based on when an ADC is sampling. The control circuitry may be configured to turn on the ADC driver during the hold phase of the ADC a time period before the track phase and to turn off the ADC driver during the hold phase a time period after the track phase. In some embodiments, the control circuitry is configured to control a duty cycle of the ADC driver turning on and off. In some embodiments, the control circuitry is configured to control a ratio between an off current and an on current in the ADC driver.
