Low-voltage, High-precision Bandgap Current Reference Circuit

摘要

A low-voltage, low-power current-mode bandgap reference is designed and simulated in standard 0.13 μrn CMOS technology on the Spectre platform. The proposed current-mode bandgap reference has a simulated temperature coefficient of 47.15 ppm/℃ over the temperature range of -40℃ to 140℃, with the corresponding current consumption of 42.06 μA complying with the specified temperature range. It could be operated down to 1.0 V of supply voltage headroom, while consuming 300 μW of power.
