Abstract
A simple MOS voltage divider uses three enhancement MOS transistors, which includes one load connected to two drivers in parallel. The gate of one driver is connected to the output node, and the other two gates are connected to the supply voltage. The transistors have a common substrate. By proper choice of the transistor geometry only, the output node voltage can be made independent of the threshold and temperature variations for output voltages larger than one threshold and smaller than one-half the supply voltage. Moreover, the ratio between the output and supply voltages remains constant.
