QDI asynchronous circuits for low power applications: a comparative study in technology FD-SOI 28 nm

چکیده
P ower consumption is becoming a critical concern in nowadays digital circuits’ design, especially for battery powered portable applications. In this context, asynchronous circuits represent one of the possible solutions for addressing power consumption issues, they can operate correctly at extremely low power supplies and are conceptually robust to PVT variation. This paper evaluates the power efficiency of a synchronous and QDI asynchronous 8-bit Arithmetic Logic Unit in FD-SOI 28nm technology. Results show that the asynchronous architecture presents a better power consumption per throughput unit relation and has maximum power efficiency at lower power supply level if compared to its synchronous counterpart.

A Review of SOI Technology and its Applications
Substrate engineering [1] has enabled the industry to overcome many of the limitations encountered by traditional scaling. As a result, device architecture and engineered substrates have become strongly coupled, a coupling that is growing stronger as the IC industry moves to the 32 nm technology node and beyond. Substrate engineering started in earnest with the industry transition to SOI wafers...
متن کاملMulti-Threshold Asynchronous Circuit Design for Ultra-Low Power
This paper presents an ultra-low power circuit design methodology which combines the MultiThreshold CMOS (MTCMOS) technique with quasi delay-insensitive (QDI) asynchronous logic, in order to solve the three major problems of synchronous MTCMOS circuits: (1) Sleep signal generation, (2) storage element data loss during sleep mode, and (3) sleep transistor sizing. In contrast to most power reduct...

In this paper, the recently proposed gate level body bias (GLBB) technique is evaluated for low voltage logic design in state-of-the-art 28 nm ultra-thin body and box (UTBB) fully-depleted silicon-oninsulator (FD-SOI) technology. The inherent benefits of the low-granularity body-bias control, provided by the GLBB approach, are emphasized by the efficiency of forward body bias (FBB) in the FD-SO...

Abstract- A novel low-voltage two-stage operational amplifier employing resistive biasing is presented. This amplifier implements neutralization and correction common mode stability in second stage while employs capacitive dc level shifter and coupling between two stages. The structure reduces the power consumption and increases output voltage swing. The compensation is performed by simple mill...
