High Performance CMOS Circuit by Using Charge Recycling Active Body-Bias Controlled SOI

摘要

In this paper, we propose a new technique for higher circuit speed without increase in leakage current by using active body-bias controlling technique. Conventional body-bias controlling techniques face difficulties, such as long transition time of body voltage and large area penalty. To overcome these issues, we propose a Charge Recycling Active Body-bias Controlled (CRABC) circuit scheme on SOI which enables quick control of body voltage by using simple additional circuit. The SPICE simulation results have shown that CRABC shortens delay time by 20 %, and transition time for controlling body-bias by 98 %.
