Abstract Demand for accommodating more and new functionalities within a single chip such as SOC needs a novel devices and architecture such as FinFET device instead of MOSFET. FinFET is emerged as non-planar, multigate device to overcome short channel effects such as subthreshold swing deterioration, drain induced barrier lowering, threshold voltage roll off which degrade circuit performance. As the need of device technology is mounting in electronic gadgets the important parameters are taken into consideration such as low leakage, high reliability, low power dissipation, and high operating speed. Reliability is one of key considerations in converting a proof of concept into reality. In this work Reliability of FinFET device is studied experimentally according to ITRS (international technology roadmap for semiconductor) roadmap using several standard test protocols such as multiple current stressing, harsher environment conditions, and effect of electromigration. Furthermore, power analysis of FinFET based SRAM is done by using 7nm bsimcmg PTM files in mentor graphics tool. The FinFET based SRAM shown low leakage, power dissipation, delay compared to existing conventional MOSFET based SRAM.

At present, sub-micro-Newton (sub-μN) micro-force in micro-assembly and micro-manipulation is not able to be measured reliably. The piezoelectric micro-force sensors offer a lot of advantages for MEMS applications such as low power dissipation, high sensitivity, and easily integrated with piezoelectric micro-actuators. In spite of many advantages above, the research efforts are relatively limited compared to piezoresistive micro-force sensors. In this paper, Sensitive component is polyvinylidene fluoride (PVDF) and the research object is micro-force sensor based on PVDF film. Moreover, the model of micro-force and sensor’s output voltage is built up, signal processing circuit is designed, and a novel calibration method of micro-force sensor is designed to reliably measure force in the range of sub-μN. The experimental results show the PVDF sensor is designed in this paper with sub-μN resolution.

Guidance Information

Strapdown seekers are superior to platform seekers for their simple structure, high reliability and light weight but cannot measure the line-of-sight angle rate information for the guidance of rotation missile directly. This paper aims at the engineering application of full-strapdown seekers on rotation missile problem. Firstly, a line-of-sight angle rate solution model is established. Based on the MATLAB, the extended Kalman filter (EKF) algorithm and unscented Kalman filter (UKF) algorithm are used to estimate the line-of-sight angle rate information of the full-strapdown seekers. The results show that using EKF filter and UKF filter both can obtain effective guidance information and the UKF’s effect is better.

In this paper, the design of a Finite Impulse Response (FIR) filter based on the residue number system (RNS) is presented. We chose to implement it in the (RNS), because the RNS offers high speed and low power dissipation. This architecture is based on the single RNS multiplier-accumulator (MAC) unit. The three moduli set {2n+1,2n,2n-1}, which avoids 2n+1 modulus, is used to design FIR filter. A numerical example illustrates the principles of residue encoding, residue arithmetic, and residue decoding for FIR filters.

Direct-Coupled FET Logic (DCFL) is an important logic family for LSI GaAs FET circuits because of its simple structure and good speed/power performance. Since it is especially sensitive to temperature shifts of performance, accurate temperature modeling is critical for design of DCFL circuits. Using a version of SPICE modified to include FET temperature dependence, the performance of DCFL is simulated over temperature and compared with measured results. In addition, an improved version of DCFL known as E-E Logic (Enhancement-Enhancement Logic) is modeled over temperature. The performance of E-E Logic is compared to DCFL with depletion-mode FET and saturated resistor loads over temperature. E-E Logic is found to offer improved yield, power dissipation and performance control compared to conventional DCFL.
