摘要： An apparatus, system, and method for voltage regulator (VR) control are provided. An apparatus can include first, second, and third comparators configured to determine whether a load voltage (VLOAD) drops below a lower non-linear control (NLC) threshold, drops below a lower linear control (LC) threshold, and exceeds an upper LC threshold, respectively. The apparatus can include power gates (PGs) configured to adjust an output voltage (VOUT) based on a provided power gate (PG) code. The apparatus can include voltage regulator (VR) controller circuitry comprising synchronous LC circuitry and asynchronous NLC circuitry, the LC circuitry configured to increment or decrement the PG code responsive to the VLOAD dropping below the LC threshold and exceeding the upper LC threshold, respectively, and the NLC circuitry configured to increase the PG code based on a number of consecutive NLC droop events and responsive to the VLOAD dropping below the lower NLC threshold.

摘要： A method and apparatus for optical signaling. In one embodiment, a laser driver converts a digital voltage sequence to a current signal having a bias mode adjustable by a bias control and a modulation mode adjustable by a modulation control. A laser generates an optical signal responsive to the current signal of the laser driver. In one embodiment, a photo-detector receives an optical signal and generates a single ended current signal. A transimpedance amplifier circuit converts the single ended current signal to a differential voltage signal. A clock recovery circuit generates an aligned clock signal and a sampler circuit uses the aligned clock signal to retrieve a digital voltage sequence.

摘要： A laser driver for high speed interconnections may convert a digital signal to a current train of a bias mode to represent logical zero and of a modulation mode to represent logical one. An optical signal thus produced may include an optical offset. An optical receiver may include a photo-detector to receive the optical signal and generate a current signal, which includes a corresponding current offset. A first amplifier stage converts the current signal to a voltage signal and a second amplifier stage generates a digital output from the voltage signal. One or more low-pass filters may be used to filter the digital output and generate a filtered offset signal for a differential amplifier to generate an offset cancellation signal. The offset cancellation signal may be provided to offset cancellation circuitry to remove the current offset from the current signal generated by the photo-detector.
