How forward body bias helps to reduce ground bouncing noise and silicon area in MTCMOS circuits: Divulging the basic mechanism

Forward body bias is an effective technique for reducing mode transition noise and area overhead associated with Multi-threshold CMOS (MTCMOS) circuits. In this paper, the principal mechanism of noise reduction and silicon area compaction in forward-body-biased MTCMOS circuits is revealed and discussed in detail. Tradeoffs between area and leakage power consumption in forward-body-biased MTCMOS circuits are evaluated. Design guidelines are provided for optimum sizing of noise-control transistor and appropriate selection of body bias voltage to fully utilize the benefits of the forward body bias technique.
