Abstract:
The present utility model relates to an ultra-low voltage two-stage ring voltage-controlled oscillator applied to a chip circuit. The oscillator includes two-stage delay units. The oscillator includes two delay units that are connected end-to-end, and adjusts a working frequency by adjusting delay time of the delay unit. The delay unit includes PMOS transistors M 1 , M 2 , M 3 , and M 4 , NMOS transistors M 5 , M 6 , M 7 , and M 8 , and a load capacitor C L . The two-stage ring voltage-controlled oscillator of the present utility model uses a substrate feed forward bias structure, reduces a threshold voltage of a transistor, reduces a supply voltage, reduces power consumption, has a large tuning range, and is particularly suitable for a system that works at a low supply voltage.
