  • Abstract
    Mixed-signal CMOS integrated circuits for future portable systems will have to operate down to supply voltages just exceeding the MOS threshold voltage. A simple CMOS circuit is reported for generating supply-voltage independent bias voltages and currents, down to a minimum supply voltage of 0.68 V (VT+2VDSat). The circuit is compatible with digital processes. Supply interference is rejected by more than 70 dB.
