Abstract: Methods and apparatus to detect an over-current in switching circuits are described. An example method to detect an over-current in a switching circuit includes randomly selecting a sensor from a plurality of sensors operatively coupled to an output stage of the switching circuit; detecting a first voltage via the randomly selected sensor; and comparing the first voltage to a reference voltage to generate a signal, wherein the signal indicates a status of the output stage of the switching circuit.

Abstract: Systems and methods are discussed for using a floating-gate MOSFET as a programmable reference circuit. One example of the programmable reference circuit is a programmable voltage reference source, while a second example of a programmable reference circuit is a programmable reference current source. The programmable voltage reference source and/or the reference current source may be incorporated into several types of circuits, such as comparator circuits, current-mirror circuits, and converter circuits. Comparator circuits and current-mirror circuits are often incorporated into circuits such as converter circuits. Converter circuits include analog-to-digital converters and digital-to-analog converters.
