Discloses are CMOS circuit designs that combine MTCMOS and hybrid
orientation technology to achieve the dual objectives of high performance
and low standby leakage power. The invention utilizes novel combinations
of a thick-oxide high-VTH PFET header with various gate- and body-biased
schemes in HOT technology to significantly reduce the performance penalty
associated with conventional PFET headers. A first embodiment of the
invention provides a HOT-B high-VTH thick oxide bulk PFET header scheme.
This header scheme can be expanded by application of a positive gate bias
VPOS (VPOS>VDD) to the HOT-B PFET header during standby mode and a
negative gate bias VNEG (VNEG
