Abstract: A microelectronic device has a common terminal transistor with two or more channels, and sense transistors in corresponding areas of the channels. The channels and the sense transistors share a common node in a semiconductor substrate. The sense transistors are configured to provide sense currents that are representative of currents through the corresponding channels. The sense transistors are located so that a ratio of the channel currents to the corresponding sense currents have less than a target value of cross-talk. The microelectronic device may be implemented without a compensation circuit which provides a compensation signal used to adjust one or more of the sense currents to reduce cross-talk. A method of forming the microelectronic device, including estimating a potential distribution in the semiconductor substrate containing the common node of the common terminal transistor, and selecting locations for the sense transistors based on the estimated potential distribution, is disclosed.

Abstract: A charge pump circuit includes a plurality of serially coupled stages and a plurality of clock drivers. A voltage output of a first of the stages is connected to a voltage input of a second of the stages. A voltage output of the second of the stages is boosted relative to a voltage input of the second of the stages. Each of the stages includes complementary charge pumps. Each of the charge pumps includes a pumping capacitor that stores charge in the stage. Each of the clock drivers drives a clock signal to the pumping capacitor of at least one of the stages. A voltage of the clock signal provided to the second of the stages is derived from the voltage input of the second of the stages.

Abstract: An apparatus, comprising: a charge-pump; a sampler that samples an optical signal, including: a black sampler; a video sampler; and an analog to digital converter. The first aspect further provides a single clock that is coupled to and provides clocking signals to: a) the charge-pump logic that is coupled to the charge-pump; and b) the sampler logic that is coupled to the sampler that samples the optical signal, wherein if the clock for the charge pump is running faster than an analog front end (“AFE”) video sampling clock, a state-machine control is configured to: skip the charge pump clock period right before a video sample signal falling edge, thereby recovering to a normal operation the next charge-pump clock period, wherein this duty cycle modulation of charge pump clock will not substantially impact charge pump output.
