Systems and Methods for Generation of Internal Chip Supply Bias from High Voltage Control Line Inputs

摘要

Systems and methods for generating internal chip supply bias from high voltage control line inputs are presented. One of a plurality of the high voltage control lines is selected and accordingly internal path switching circuitry is enabled to pass the selected high voltage control line while protecting the associated components from over-stress.

1. An integrated circuit comprising:
an internal integrated circuit supply node; a plurality of individually selectively activatable transistor arrangements inclusive of pass transistors for selectively passing respective input control voltages to the internal integrated circuit supply node in order to supply power to the integrated circuit; and a corresponding plurality of individually controllable biasing arrangements for biasing respective pass transistors of the transistor arrangements, the biasing arrangement being configured to prevent voltage over-stress of the biased pass transistors.
