This paper highlights a 14nm Analog and RF technology based on a logic FinFET platform for the first time. An optimized RF device layout shows excellent Ft/Fmax of (314GHz/180GHz) and (285GHz/140GHz) for NFET and PFET respectively. A higher PFET RF performance compared to 28nm technology is due to a source/drain stressor mobility improvement. A benefit of better FinFET channel electrostatics can be...
Salt and pepper noise removal is extremely challenging task when the noise density is very high in the corrupted image. Usually the existing filters are not capable of removing this noise above 70% density. This paper proposes a Sequentially Combined Mean-Median Filter (SCMMF) based on combination of arithmetic mean and median technique. A binary flag image is generated with the help of identified...
An exhaustive method for verifying & optimizing the performance of high frequency mirror inverter for induction heater is presented here. Heating coil of the induction heater is made of litz wire which controls the skin effect and proximity effect of conductor operating at high frequency. With the calculated optimum values of inductance and resistance at a particular operating frequency, HF mirror...
Automotive and consumer multi-channel 24 b audio systems have demanded low-cost digital-to-analog converters (DACs) which offer wide dynamic range, high linearity, small die size, and low power consumption such that the system can be housed in a small low-cost plastic package. Several 120 dB SNR audio ΔΣ DACs have been reported using either switched-capacitor or continuous-time techniques. This paper...
A modeling method for computing the inductance and AC resistance of litz-wire for a household purpose induction cooker is presented. Litz wire construction controls the skin effect and proximity effect of conductor operating at high frequency. Both inductance and AC resistance of the twisted litz wires are calculated by varying the number of strands and layer construction. An attempt is also made...
Developing efficient handwriting recognition systems that are fast and highly reliable is a challenging problem. This work represents the development of an online handwriting recognition system for Bangla script, widely used in eastern India and Bangladesh. In our approach, an online handwritten character/cluster is characterized by structure or shape based representation of a stroke in which a stroke...
We have assembled molecular multi-level switches (0, 1, 2, 3) on an atomically flat metallic substrate (Figure 1 a). The molecules self-assemble in the form of an organic bi-layer. Each molecule functions as a cellular automata (CA) cell when assembled in an ordered pattern, otherwise they are conductance switch. The molecular bi-layer satisfies three fundamental criteria of cellular automaton circuitry...
We propose a novel testing approach that combines information from UML sequence models and state machine models. Current approaches that rely solely on sequence models do not consider the effects of the message path under test on the states of the participating objects. Dinh-Trong et al. proposed an approach to test input generation using information from class and sequence models.We extend their...
We present a novel testing approach that combines information from UML sequence models and state machine models. We use sequence models to extract message paths that play a role in critical usage scenarios of a system. We use state machines to generate multiple execution paths from a message path by analyzing the effect of the messages on state transitions of the system. By covering these execution...
Time-domain terahertz spectroscopic studies of the quasi-one-dimensional material PtI(en) reveal a highly anisotropic complex refractive index, including a strongly polarized infrared-active phonon absorption at 2.24 THz corresponding to modulation of the charge-density-wave structure.

Previously reported multi-bit oversampling DeltaSigma audio DACs use 2-level (+1, -1) unit elements in either switched-capacitor or current-steering form. This paper presents a low-power audio DAC that uses a 3-level current-steering unit element architecture.

In this study, a finite element code based on a combination of equivalent single-plate theory and classical laminated plate theory was used to study the dynamic behavior of the thin film membrane structures. The structure studied was piezoelectric micromachined ultrasonic transducer (pMUT) fabricated with MEMS technology. The membrane has two different shapes, square and rectangular. Two different...
The objective of the current study is to investigate the size effect on the performance of piezoelectric micromachined ultrasonic transducers (pMUTs). pMUTs with twenty different dimensions were designed and fabricated. The length/width aspect ratios of the membranes range from 5 to 22. For each design, multiple samples were fabricated in order to collect statistically meaningful data. The performance...
The DC characteristics of InGaAs-InP single heterojunction bipolar transistors (SHBTs) were studied for the first time under high energy (/spl sim/1 MeV) electron radiation with a cumulative dose up to 5.4/spl times/10/sup 15/ electrons/cm/sup 2/. The following degradation effects were observed for electron doses greater than 10/sup 15//cm/sup 2/: (1) decrease in collector current, (2) decrease in...
