Minimal power start-up circuit design for self-biased CMOS current generators

摘要

A new start-up circuit configuration, with minimal standby power dissipation, is proposed for CMOS self-biased current generators. Using standard 0.13 μm CMOS technology, simulation results show that for a supply voltage range 1.8 V to 2.5 Vand a temperature range -40℃ to ＋85℃, the circuit standby power dissipation is less than 20 nW.
