A Family of Compact Trim-Free CMOS Nano-Ampere Current References
2019
This paper introduces a family of three resistor-less low-power, low-area and trim-free current references with low PVT sensitivity. The proposed current sources achieve tens of nano-Ampere current consumption with a temperature coefficient down to 182ppm/°C. The proposed family of current sources are enabled to operate within the 3.3V I/O voltage domain, to avoid additional power consumption from internal regulation, and they are implemented in a 180nm standard logic CMOS process.
