In order to combat the exponentially growing leakage power in modern microprocessors, researchers have proposed the use of alternative power-gating structures that can yield higher leakage savings with a much lower performance impact. A prime contender is an emerging CMOS-compatible power-gating device, the nanoelectromechanical systems (NEMS) switch. Compared to transistors, NEMS switches have zero...
Power Gating(PG) is very effective to reduce the leakage power. Recently proposed Zigzag power gating(ZPG) technique has the visible advantage on short wake-up time. However, additional PG transistors consume intolerable area overhead. Basing on the BPTM-65nm model, we propose a new optimization methodology of the selective ZPG technique for the wide-used dual-threshold voltage CMOS circuit design...
Polymorphic gates can be considered as a new reconfigurable technology capable of integrating logic functions with sensing in a single compact structure. Polymorphic gates whose logic function can be controlled by the level of the power supply voltage (Vdd) represent a special class of polymorphic gates. A new polymorphic NAND/NOR gate controlled by Vdd is presented. This gate was fabricated and utilized...
This paper describes a design flow for the circuit-level optimization of a technology. The concurrent exploration of device characteristics and library design choices leads to a more application-optimal technology. We illustrate the design flow by: 1) analyzing the impact of buffer cell design, and 2) by optimizing a 130 nm technology for low operational power.
