Abstract: Scaling supply voltage of FinFET circuits is an efficient method to achieve low power dissipation. Superthreshold FinFET logic circuits can attain low power consumption with favorable performance, because FinFET devices operating on medium strong inversion regions can provide better drive strength than conventional CMOS transistors. The supply voltage of the super-threshold circuit is...

This paper presents a low voltage low power RF/analog front-end circuit for passive ultra high frequency (UHF) radio frequency identification (RFID) tag. Temperature compensation is achieved by a reference generator using sub-threshold techniques which requires lower supply voltage than conventional bandgap circuit. Some novel structures are developed to construct the building blocks, including...

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...

New low-power Level Shifter (LS) circuit is designed by using sleep transistor with Multi Threshold CMOS (MTCMOS) technique for robust logic voltage shifting from sub-threshold to abovethreshold domain. MultiSupply Voltage Design (MSVD) technique is mainly used for energy and speed in modern system-on-chip. In MSVD, level shifters are required to allow different voltage supply to shift from the...

The design of bandgap-based voltage references in digital CMOS raises several design difficulties, as the supply voltage is lower than the silicon bandgap in electron volts, i.e., 1.2 V. A current-mode architecture is used in order to address the main issues posed by the low supply, but the implementation of the operational amplifier and of dedicated startup circuits deserves some attention. Ev...

A low-power, low-phase-noise quadrature oscillator for Medical Implantable Communications Service (MICS) transceivers is presented. The proposed quadrature oscillator generates 349~689 MHz I/Q (In-phase and Quadrature) signals covering the MICS band. The oscillator is based on a differential pair with positive feedback. Each delay cell consists of a few transistors enabling lower voltage operat...

This paper presents a novel circuit architecture for implementing analog Turbo-style decoders in subthreshold CMOS with low supply voltage.
