Abstract
A voltage generating circuit for generating a plurality of associated voltages includes a constant current source for generating a constant current; a plurality of resistors connected in series to the constant current source in series for generating a plurality of associated reference voltages; and a first controlled switch connected to a first resistor in parallel, wherein the plurality of associated reference voltages are changed by optionally conducting the first controlled switch to control the flow of the constant current through the first resistor.
