摘要

A zero quiescent current startup circuit with automatic turning-off for low power current and voltage reference is presented. The proposed startup uses positive feedback to sense an internal bias voltage of the main current/voltage reference circuit and guarantees it properly achieves its desired steady state condition. After that, the start-up circuitry automatically turns off itself. Hence, there is no power consumption on start-up circuitry after start-up process. Also, its very robust architecture is compatible with standard CMOS processes and is able to operate down to sub-IV making it ideal for single battery applications. The circuit has been integrated in a 45nA current source implemented in TSMC 0.25um process. Transient response of the start-up circuitry has been measured as well as supply voltage variation has been evaluated to prove start-up operation.
