The paper presents a sub-lV current-mode bandgap reference (BGR) for low-supply voltage system-on-chips (SOCs). The proposed BGR uses an amplifier with input butter to relax the biasing requirements of the transistors, avoiding the native transistors and low-threshold devices. Fabricated in standard 65 nm CMOS technology, the circuit occupies an area of 0.02 mm2. The BGR provides an output reference voltage of 571 mV while operating with a low supply voltage of 1.04 V. Integrated into a receiver operating at 1.2 V power supply, the BGR consumes a current of 182.3 μA.
