  • Publication number: 20140340120
    Abstract: A phase detection circuit can include two phase detectors that each generate a non-zero output in response to input signals being aligned in phase. The input signals are based on two periodic signals. The phase detection circuit subtracts the output signal of one phase detector from the output signal of the other phase detector to generate a signal having a zero value when the periodic signals are in phase. Alternatively, a phase detector generates a phase comparison signal indicative of a phase difference between periodic signals. The phase comparison signal has a non-zero value in response to input signals to the phase detector being aligned in phase. The input signals are based on the periodic signals. An output circuit receives the phase comparison signal and generates an output having a zero value in response to the periodic signals being aligned in phase.

    Abstract: In an integrated-circuit image sensor, binary sample values are read out from an array of pixels after successive sampling intervals that collectively span an image exposure interval and include at least two sampling intervals of unequal duration. Each pixel of the array is conditionally reset after each of the successive sampling intervals according to whether the pixel yields a binary sample in a first state or a second state.

  • Publication number: 20140267884
    Abstract: Methods and systems for increasing the effective dynamic range of an image sensor are disclosed. Each pixel in the sensor is exposed for a respective first exposure time. Each pixel's response to the respective first exposure is measured and compared to threshold values. Based on the pixel's response to the respective first exposure time, an optimal exposure is calculated for each pixel. The optimal exposure time is applied to each pixel by utilizing row-enabled and column-enabled signals at each pixel within the sensor.

    Abstract: One embodiment relates to a receiver with both decision feedback equalization and on-die instrumentation. A clock data recovery loop obtains a recovered clock signal from an input signal, and a first sampler, which is triggered by the recovered clock signal, generates a recovered data signal from the input signal. A phase interpolator receives the recovered clock signal and generates a phase-interpolated clock signal. A second sampler is triggered by the recovered clock signal in a decision feedback equalization mode and by the phase-interpolated clock signal in an on-die instrumentation mode. Other embodiments and features are also disclosed.

  • Patent number: 8441820
    Abstract: A control system for a multilevel converter includes a differential mode current regulator, a neutral point (NP) controller and a PWM controller for generating switching pulses for the multilevel converter. The differential mode current regulator generates reference voltage command signals based on a difference between reference current command signals and actual current command signals, and the NP controller determines a modified neutral point current signal in response to a DC link voltage unbalance. The NP controller utilizes the modified neutral point current signal to generate a common mode reference voltage signal. The switching pulses are generated by the PWM controller based on the reference voltage command signals and the common mode reference voltage signal.

  • Patent number: 8395919
    Abstract: A power inverter system includes a DC to AC inverter configured to convert DC voltage from a DC power source to AC voltage. A DC link couples the DC power source and the inverter. An inverter pre-charger operates to pre-charge the inverter to achieve a desired DC link voltage prior to connecting the power inverter system to an AC power grid. A phased lock loop synchronizes the pre-charged inverter to the AC power grid prior to connecting the power inverter system to the AC power grid. The pre-charged inverter regulates the DC link voltage to about the minimum voltage level that allows control of AC grid currents via the inverter subsequent to connecting the power inverter system to the AC grid. The inverter operates in a maximum power point tracking control mode only subsequent to a first voltage transient caused by connecting the DC power source to energize the power inverter system.
