摘要：
Reduced passives size and improved quality factor (Q) for an on-chip inductor can be achieved in a fully integrated DC/DC power converter by high frequency switching. This paper presents a high speed closed-loop buck converter that uses phase locking control system to reduce output voltage ripple. A closed-loop DC/DC power converter has been designed in a TSMC-0.25 mu m technology. The power converter takes a 3.3 V DC input and switches at 1.02 GHz to produce output voltage of 1.5 V and 1.8 V DC and stabilizes in less than 600 ns. Design equations and simulation results are presented.
