This Bandgap Reference (BGR) IP is an ultra-low-power, sub-1V analog voltage reference generator designed for integration in advanced mixed-signal SoCs. It generates temperature- and supply-stable reference voltage suitable for low-voltage, low-power applications such as biomedical front ends, IoT sensor nodes, and DRAM PIM systems. The IP operates entirely in the analog domain, taking a single supply voltage as input and producing a precise reference voltage output. It does not require any digital control interface. Internally, it includes a proportional-to-absolute-temperature (PTAT) current generator, a complementary-to-absolute-temperature (CTAT) reference path, and a high-gain two-stage operational amplifier. A dedicated startup circuit ensures reliable initialization under all process, voltage, and temperature conditions. The feedback structure enhances loop stability and provides strong immunity against supply and temperature variations. The design emphasizes high PSRR and a low temperature coefficient, supporting robust performance in environments with fluctuating supply and ambient conditions. The IP is implemented in a standard CMOS process and features a compact layout area, making it well-suited for highly integrated, battery-powered systems and always-on analog blocks.
