摘要： A digital phase-locked loop (DPLL) may include a time-to-digital converter (TDC) to provide a phase error signal, a frequency-divider to perform frequency division on an output signal to generate a frequency-divided output signal, a delta-sigma-modulator (DSM) to provide a test signal that represents a quantization error of the DSM, and a digital-to-time converter (DTC) to at least partially remove the quantization error from the frequency-divided output signal based on the test signal to generate the feedback signal. The DPLL may include a circuit to cause the DTC to provide a percentage of the quantization error such that the percentage of the quantization error is in the phase error signal, and a TDC calibration component to calibrate the TDC by applying a gain adjustment factor to the TDC. The gain adjustment factor may be based on the test signal and the phase error signal including the percentage of the quantization error.

摘要： A circuit for controlling a switch of a power converter includes a first clock signal generator configured to generate a first clock signal and a switching signal generator configured to generate a switching signal to control the switch of the power converter based on the first clock signal. The circuit further includes error detection circuitry configured to output an error indication and a second clock signal generator configured to generate, in response to the error indication, a second clock signal that comprises an edge of a clock cycle of the second clock signal that corresponds to when the switching signal deactivates the switch of the power converter plus a time delay. The switching signal generator is configured to generate the switching signal to control the switch of the power converter further based on the second clock signal in response to the error indication being output by the error detection circuitry.

摘要： A switching device includes first and second RF terminals disposed over a substrate, one or more strips of phase change material connected between the first and second RF terminals, a region of thermally insulating material that separates the one or more strips of phase change material from the substrate, and a heater structure comprising one or more heating elements that are configured to control a conductive connection between the first and second RF terminals by applying heat to the one or more strips of phase change material. Each of the one or more strips of phase change material includes a first outer face and a second outer face opposite from the first outer face. For each of the one or more strips of phase change material, at least portions of both of the first and second outer faces are disposed against one of the heating elements.
