  • Patent number: 11467192
    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 is 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.
