Abstract: Embodiments of phase-generation circuitry and methods for generating a multiphase signal with duty-cycle correction are generally described herein. The phase-generation circuitry may include a plurality of controllable delay stages arranged in series and phase detector circuitry. Each delay stage may be configured to phase shift a differential signal based on a control signal. The phase detector circuitry may be configured to generate the control signal based on a first time difference and a second time difference. The first time difference may be a time difference between rising edges of a first component of the differential signal and a second component of a phase-shifted signal. The second time difference may be a time difference between falling edges of the first component of the differential signal and the second component of the phase-shifted signal. Other circuits, systems, and methods are described.

Abstract: Embodiments of a multiphase generator with duty-cycle correction are generally described herein. In some embodiments, the multiphase generator comprises controllable delay stages arranged in series and dual-edge phase detector circuitry. The dual-edge phase detector circuitry may generate a control signal to adjust the delay provided by the delay stages based on corresponding rising edges and corresponding falling edges of same-state signals operated on by the delay stages. Other circuits, systems, and methods are described.

Abstract: Disclosed is a system including a substrate having a first side and a second side and a layer of photoacoustic material disposed on the first side of the substrate. The layer of photoacoustic material is configured to generate a directional ultrasound wave in response to a laser beam impinging on the layer. A conduit may be coupled to the housing and have an opening adjacent to the layer of photoacoustic material; the directional ultrasound wave may be directed through fluid that is contained in the conduct to generate a liquid jet in a liquid.

Abstract: A driving circuit for controlling power of a light-emitting diode (LED) light source includes a transformer, a switch controller, and a dimming controller. The transformer has a primary winding that receives input power from an AC/DC converter and a secondary winding that provides output power to the LED light source. The switch controller coupled between an optical coupler and the primary winding receives a feedback signal indicative of a target level of a current flowing through the LED light source from the optical coupler, and controls input power to the primary winding according to the feedback signal. The dimming controller coupled to the secondary winding receives a switch monitoring signal indicative of an operation of a power switch coupled between an AC power source and the AC/DC converter, and regulates the output power by adjusting the feedback signal according to the switch monitoring signal.
