Architectures and arithmetic for low static power consumption in nanoscale CMOS
(2009) In VLSI Design Abstract
 This paper focuses on leakage reduction at architecture and arithmetic level. A methodology for considerable reduction of the static power consumption is shown. Simulations are done in a typical 130 nm CMOS technology. Based on the simulation results, the static power consumption is estimated and compared for different filter architectures. Substantial power reductions are shown in both FIRfilters and IIRfilters. Three different types of architectures, namely bitparallel, digitserial, and bitserial structures are used to demonstrate the methodology. The paper also shows that the relative power ratio is strongly dependent on the used word length, i.e. the gain in power ratio is larger for longer word lengths. A static power ratio at... (More)
 This paper focuses on leakage reduction at architecture and arithmetic level. A methodology for considerable reduction of the static power consumption is shown. Simulations are done in a typical 130 nm CMOS technology. Based on the simulation results, the static power consumption is estimated and compared for different filter architectures. Substantial power reductions are shown in both FIRfilters and IIRfilters. Three different types of architectures, namely bitparallel, digitserial, and bitserial structures are used to demonstrate the methodology. The paper also shows that the relative power ratio is strongly dependent on the used word length, i.e. the gain in power ratio is larger for longer word lengths. A static power ratio at 0.48 is shown for the bitserial FIRfilter and a power ratio at 0.11 is shown in the arithmetic part of the FIRfilter. The static power ratio in the IIRfilter is 0.36 in the bitserial filter and 0.06 in the arithmetic part of the filter. It is also shown that the use of storage, such as registers, relatively the arithmetic part affects the power ratio. The relatively lower power consumption in the IIRfilter compared to the FIRfilter is due to the lower use of registers. (Less)
