A sub-1V bandgap voltage reference (BGVR) in 0.16μm CMOS is presented that circumvents the trade-off between area and power consumption in conventional sub-1V BGVR topologies.
This circuit can be used in systems to generate reference voltages locally, eliminating the conventional relatively large BGVR and its global reference voltage distribution interconnect.
The active area is 0.0025mm2; at 295K, VREF=0.94V with σ=0.8% at a minimum supply voltage of 1.1V, with 1.4μA supply current.
