Title: Power consumption suppression circuit for low voltage dynamic logic
Inventor: ZEN GENKEI
IPC: H03K19/00
Filed: 2001-02-15
Abstract: PROBLEM TO BE SOLVED: To provide a power consumption suppression circuit for low voltage dynamic logic that can efficiently reduce power consumption due to a sub- threshold leakage current without increasing the chip area. SOLUTION: Since an NMOS transistor(TR) Mnb is turned on when a level of an output OUT of an output node 50 of a dynamic logic circuit 100 is at a high level, a reduced voltage VBB smaller than a ground voltage VSS is applied to a back gate of a MOS TR and an NMOS TR Mn1 of an n-logic 10. On the other hand, when the level of the output OUT is at a low level, since a PMOS TR Mpp is turned on, a boosted voltage VPP higher than a power supply voltage VDD is applied to a back gate of an PMOS TR Mp1. Thus, the effective threshold voltage of the MOS TRs Mp1, Mn1 of the dynamic logic circuit 100 can be increased.
