In the midst of technological advance where everything is connected via the internet, IoT is emerging as a potential solution to everything, ranging from health wearables to smart city. An RFEH power management system has promising benefits that could further improve the powering of IoT devices as it has potential for clean energy as well as other advantages which consists of a rectifier, bandgap reference and LDO as the main core. However, the main challenge is supplying clean and low noise power to sensitive circuits such as low power sensors, VCOs and PLLs. A high PSRR bandgap reference that rejects noise at the power supply is needed so that the circuitry powered by RFEH systems would be able to function properly. This paper presents a bandgap with MOS PTAT and CTAT extraction achieving a PSRR of -81dB at a V<sub>ref</sub> of 0.415V was designed on 130nm CMOS technology targeting IoT RFEH devices that operate at sub-threshold and near-threshold region that exhibits improvement over the base design.

The design of a low-noise and low-power second-order bandgap reference voltage source using a linear combination of two base-emitter voltages with only one scaling factor is treated. The design takes into account the temperature dependency of the resistors and the finite current gain of BJT�s. The circuit is integrated in a CMOS process. The output voltage is approximately 140 mV with an average temperature dependency of 22.5 ppm/K in the range of 0�C to 120�C. Its equivalent output noise voltage is 57.6nV/vHz. The total current consumption is about 115 �A from a 2V voltage-supply.Keywords: bandgap reference, negative feedback, systematic design.
