A 9.3 nW all-in-one bandgap voltage and current reference circuit using leakage-based PTAT generation and DIBL characteristic

摘要

This paper presents a sub-10 nW bandgap reference (BGR) circuit that implements both voltage and current references in one circuit. The BGR circuit was implemented with a 0.18μm CMOS process and generates voltage and current references of 1.238 V and 6.64 nA while consuming 9.3 nW. The voltage and current references show standard deviations of 0.43 % and 1.19 % with temperature coefficients of 26 ppm/°C and 283 ppm/°C, respectively.
