Abstract Aiming at the disadvantage of high-power consumption and a long start-up time traditional Pearce driver circuit, 32.768KHz crystal circuit is designed, which can effectively reduce power ensure fast start. The simulation results show that, under voltage 1.1 V, vibration 0.5 ms, output amplitude about 250 mV, static current 48.6 nA, 53.5nW. This drive has characteristics start, stable o...

The use of power control (PC) and discontinuous transmission (DTx) can reduce the average power consumption of mobile base stations (BS). In this paper, the power consumption of a picocell or a femtocell are analyzed in a time division multiple access (TDMA) scenario. The minimization of the power consumption is viewed as a constrained optimization problem and a closed form of the compromise be...

The power consumption of the network-on-chip communication backbone is explored and the effectiveness of low-power encoding and error protection techniques is analysed. For the switch under the study, a Nostrum deflective routing switch, simulations and power analysis suggest that only a minor fraction of the power is dissipated in the logic blocks, whereas the major part is due to the intercon...

Portable applications such as mobile phones, pagers, and PDAs are continually growing in sophistication. This places an increasing burden on the embedded microprocessor to provide high performance while retaining low power consumption and small die size. The ARM7TDMI microprocessor has been highly successful in these application areas. However, as products grow in complexity more processing pow...

Power consumption is becoming the key aspect in modern digital systems design. The current low-power design flow involves the application of some power-reduction techniques in an RTL (Register Transfer Level) or lower-level model. This paper describes a novel methodology for low-power design flow that supplements the existing one. It proposes an abstract form of the power-intent specification b...

ZigBee is a recent wireless networking technology built on IEEE 802.15.4 standard and designed especially for low-data rate and low-duty cycle applications such as home and building automation and sensor networks. One of the primary goals of ZigBee is low power consumption and therefore long-living networks. Despite this goal, current network formation and routing protocols described in the Zig...
