Objective
The main objective of this project is to overcome the biasing issues in conventional BGR by using buffer at the amplifier input.
Abstract
This paper presents a sub-1V current-mode bandgap reference (BGR) for low-supply voltage system-on-chips (SOCs). The proposed BGR uses an amplifier with input buffer to relax the biasing requirements of the transistors, avoiding the native transistors and low-threshold devices. Fabricated in standard 45 nm CMOS technology. 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 in µA. All the designs are implemented in Tanner EDA using 45 nm technology .
Index Terms—Bandgap reference, CMOS, temperature compensation, voltage reference.
