  • Publication number: 20210051283
    Abstract: An image sensor may include an array of image pixels that is coupled to column readout circuitry, which may read out charge generated by the image pixels. The column readout circuitry may include a column amplifier having analog memory cells. The analog memory cells may include a high gain capacitor and a low gain capacitor coupled in parallel between a column of the image pixels and an input of the column amplifier. A feedback capacitor may be coupled between the input and an output of the column amplifier. High and low gain select switches respectively coupled to the high and low gain capacitors may allow for the output of high and low gain reset values and image signals, which may be used in correlated double sampling operations and which may increase the dynamic range of the image sensor.

  • Patent number: 9735765
    Abstract: Embodiments include apparatuses, methods, and systems for jitter equalization and phase error detection. In embodiments, a communication circuit may include a data path to pass a data signal and a clock path to pass a clock signal. A jitter equalizer may be coupled with the data path and/or clock path to provide a programmable delay to the data signal and/or clock signal, respectively. The delay may be determined by a training process in which a supply voltage may be modulated by a modulation frequency. The delay may be dependent on a value of the supply voltage, such as a voltage level and/or jitter frequency component of the supply voltage. A phase error detector is also described that may be used with the communication circuit and/or other embodiments.

  • Patent number: 9577523
    Abstract: A dual mode voltage regulator according to one embodiment includes a passive regulator circuit, a switching regulator circuit, and a controller circuit configured to determine parameters of an external select input. The controller is configured to selectively couple, on a cold boot up, either the passive regulator circuit or the switching regulator circuit between an input voltage port and an output load based on the determination of parameters.

  • Patent number: 9343963
    Abstract: A dual mode voltage regulator according to one embodiment includes a passive regulator circuit; a switching regulator circuit; and a controller circuit configured to monitor operational parameters of the dual mode voltage regulator and selectively couple either the passive regulator circuit or the switching regulator circuit between an input voltage port and an output load. The selective coupling is based on the monitoring of parameters including current through the output load, voltage at the input voltage port and voltage at the output load as well as the availability of a system clock signal.

  • Publication number: 20160066724
    Abstract: Embodiments described herein relate generally to monitoring a dining session using smart smallwares. A smart smallware may sense usage or non-usage associated with a dining session of a customer. Based on the sensed non-usage of the smart smallware, the smart smallware may detect a period of inactivity. In response to the detected period of inactivity, the smart smallware may transmit an indication of the detected period of inactivity. This transmitted indication may cause an external monitoring device to notify a waitperson that a customer associated with that smart smallware may require attention. Other embodiments may be described and/or claimed.

  • Publication number: 20030203725
    Abstract: A circuit stage such as an input stage is provided for a radio frequency tuner having an input which typically receives a broadband signal comprising many channels. The input stage comprises a low noise amplifier in the form of a long tail pair of transistors and a controllable tail current source. A level detector detects the signal level at the input of the amplifier and controls the tail current source so as to increase the tail current as the signal amplitude rises above a threshold level and so as to keep the tail current fixed when the signal amplitude is below the threshold.
