PROJECT TITLE :

A Low-Power Forward and Reverse Body Bias Generator in CMOS 40 nm - 2018

ABSTRACT:

This temporary presents a coffee-power forward and reverse body bias (FRBB) generator with body bias (BB) switches to dynamically set BB voltage. The reverse BB (RBB) P-well generator uses pulse frequency modulation (PFM)-primarily based switching capacitor power converter to achieve low power consumption during a wide load current vary of 1-thirty µ A. The FBB adopts category-AB output stage and an over-current indicator to detect large body diode forward conduction leakage current. BB switch is introduced to dynamically configure the FRBB generated voltage. The proposed FRBB with BB switch is fabricated in an exceedingly CMOS forty-nm triple well process, occupying an area of around zero.1 mm 2 . The 300k digital gates are used because the load for check. The measured active current for FBB and RBB are thirteen and five µA, respectively.
