Title: BIAS GENERATOR FOR A LOW CURRENT DIVIDER
Abstract:
A voltage divider is protected from current paths created by parasitic devices. The voltage divider includes a first string of diode-connected MOS transistors and a second string of diode-connected MOS transistors. A substrate bias terminal of each transistor in the first string is coupled to a substrate bias terminal of a corresponding transistor in the second string. The first string of transistors provides an output voltage which is protected from current paths created by parasitic devices.
