Adiabatic logic saves energy compared to static CMOS by charging the outputs efficiently and by recovering charge from the outputs. For the most promising adiabatic logic families a four phase power-clock is used, that can be generated in an energy efficient manner by using a synchronized 2N2P LC oscillator. Different input patterns to the circuit lead to different capacitive loads seen by the oscillator...
Due to increasing range and sophistication of battery-operated applications and rising power densities due to shrinking, low-power design has become a main issue in modern CMOS technologies. One way to reduce the dissipated energy is to apply a circuit style known as adiabatic logic, that operates most efficient at moderate frequencies around 100 MHz and saves more than 80% of the energy compared...
Fine-grained sleep transistor circuits are demonstrated with 0.12 /spl mu/m 16 b MAC (multiply-accumulate unit). Standby power is reduced by a factor of 5500 at 85/spl deg/C with speed reduction of 5%. Charge recycling reduces the minimum sleep time by 25%. Dynamic power dissipation decreases by 16% activating a fraction of the switch in slow mode. Double switching inhibits power-on glitches and reduces...
