Base paper abstract:
This article presents a low-power bandgap reference (BGR) featuring high power supply rejection ratio (PSRR) and fast start-up capability, operating across a wide supply voltage range of 1.3–5 V. A novel pre biased pulse current injection technique is proposed in the start-up circuit, achieving a 1% settling time of 50 µs and a 25× speed gain during start-up. To enhance supply noise immunity, the proposed BGR employs a pre regulated (PR)-based amplifier that effectively decouples the reference voltage from supply voltage fluctuations. Fabricated in a 0.18-µm BCD process, the proposed reference occupies an active area of 0.0394 mm 2. Under a 5 V supply, the circuit generates a 1.2 V reference voltage while consuming only 48 nA quiescent current. Operating down to a minimum supply voltage of 1.3 V, it maintains a low power consumption of 57.2 nW at room temperature. The reference exhibits an average temperature coefficient (TC) of 5.95 ppm/◦C across a wide temperature range (−40◦C to 125◦C) and achieves an outstanding line sensitivity (LS) of 0.00308%/V over the 1.3–5 V supply range. Furthermore, the measured PSRR reaches −85 dB at 100 Hz. Index Terms: Bandgap reference (BGR), pre bias pulse current injection, power supply rejection ratio (PSRR), start-up, ultralow-power (ULP).

Proposed abstract:
Bandgap reference circuits are essential in low-power sensors, biomedical devices, IoT nodes, and mixed-signal SoCs because they provide a stable, temperature-independent voltage for ADCs, regulators, and bias networks. However, when implemented in deep-submicron CMOS such as 45 nm, classical BGR designs suffer from higher leakage, reduced analog gain, poor PSRR, and slow start-up. To overcome these issues, the proposed work redesigns the bandgap reference by preserving the PTAT/CTAT core while improving the pre-regulated amplifier and introducing an RC-filtered prebias start-up network. The RC filter reduces supply-coupled noise, smooths the injected start-up pulse, and stabilizes the internal nodes, which strengthens the VREF output during settling and improves overall PSRR. With this optimized start-up and regulation scheme, the redesigned BGR achieves robust noise immunity, reliable fast start-up, and enhanced VREF stability in 45 nm CMOS. Tanner EDA simulations confirm proper temperature behaviour, PSRR improvement, start-up performance, and low quiescent power, demonstrating suitability for modern low-power integrated systems.
