In this paper, we propose an Active Body-biasing Controlled (ABC)-Bootstrap PTL (Pass-Transistor Logic) on PD-SOI for ultra low power design. Although simply lowering the supply voltage (VDD) causes a lack of driving power, our boosted voltage scheme employing a strong capacitive coupling with ABC-SOI improves a driving power and allows lower voltage operation. We also present an SOI-SRAM desig...

The paper presents the implementation of a standard cell multigate fully synthesizable rail-to-rail dynamic voltage comparator. comparator works on deep sub-threshold supply VDD =0.3 V with common mode inputs. common-mode input range is VDD/2 minimum offset ranging between 8mV to 28mV. Thus circuit simulated at 180nm Complementary Metal-Oxide Semiconductor (CMOS) process. Hence has measured and...

This paper proposes a novel design method to minimize the leakage power during standby mode using a novel optimal supply voltage and body-bias voltage generating technique for nanoscale VLSI systems. The minimum level of VDD is generated for different temperature and process conditions adaptively using a look-up-table method. The subthreshold current as well as gate-tunneling and bandto-band-tu...

The design of Low Power Systems-on-Chips (SoC) in very deep submicron technologies becomes a very complex task that has to bridge very high level system description with low-level considerations due to technology defaults and variations and increasing system and circuit complexity. This paper describes the major low-level issues, such as dynamic and static power consumption, temperature, techno...

Aggressive voltage scaling to 0.5V and below is gaining attention due to the interest of using solar cells for portable systems. Static swapped-body biasing [1] and ultra-dynamic voltage scaling (UDVS) [2] are two representative designs in this respect. However, neither of them offers comprehensive treatment of the related design problems. This paper presents a 230-to-500mV 32b RISC core design...

Vitamin D deficiency is pandemic, yet it is the most under-diagnosed and under-treated nutritional deficiency in the world. Paucity of literature on vitamin D status in population more than 50 years of age also warrants this study. The aim is to assess the vitamin D status in individuals above 50 years of age and to study correlation of Vitamin D Levels with Biochemical parameters among them. T...

This Minimum Distance ID-Search Engine (MDSE) realizes the pattern-matching hardware accelerator for the portable multimedia and intelligent processing systems. The chip executes highly parallel computation of L,-norms between an input key and stored multiple reference records, and search of the minimum distance among them in 1 dimensional (1D) memories. According to architectural-level power e...

We deene a network break as a break fault in the p-network or in the n-network of a CMOS cell that breaks one or more transistor paths between the cell output and Vdd or GND. Previous work, mostly in the context of transistor stuck-open faults, studied test invalidation due to transient paths to Vdd or GND, and due to charge sharing. In this paper we show the importance of Miller feedthrough an...
