摘要： Systems and methods are discussed for using a floating-gate MOSFET (520) as a programmable reference circuit. One example of the programmable reference circuit is a programmable voltage reference source (705), while a second example of a programmable reference circuit is a programmable reference current source (805). The programmable voltage reference source (705) and/or the reference current source (805) may be incorporated into several types of circuits, such as comparator circuits, current-mirror circuits (900), and converter circuits. Comparator circuits and currentmirror circuits are often incorporated into circuits such as converter circuits. Converter circuits include analog­to-digital converters (700, 175) and digital-toanalog converters (800, 100).
