ABSTRACT:
A circuit device for selecting operating modes using a single reference pin that uses current rather than voltage in an electronic subsystem. An operating mode is selected by modulating the input bias current over a range of values. A specific range is associated with a given function so that a value of current can assume a parametric input into the subsystem. The circuit has widespread application since current can be modulated faster than voltage and it eliminates the need for multiple voltage reference points.
