We have developed the effective algorithm for detecting digital binary phase-shift keyed signals. This algorithm requires a small number of arithmetic operations over the signal period. It can be relatively easy implemented based on the modern programmable logic devices. It also provides high interference immunity by identifying signal presence when signal-to-noise ratio is much less that its w...

Classically, an energy detector is implemented in time domain (TD). However, frequency domain (FD) based energy detector has demonstrated an improved performance. This paper presents a comparison between the two approaches as to analyze their pros and cons. A detailed performance analysis of the classical TD energy-detector and the periodogram based detector is performed. Exact and approximate ...

Cerebral hemorrhage is an important clinical problem that is often monitored and studied with expensive techniques, such as computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET). These devices are not readily available in economically underdeveloped regions of the world and in emergency departments and emergency zones. The magnetic inductive method i...

In this paper a vital component of communication system, a general purpose analog Phase lock loop (PLL) is modeled using a novel combinational approach which apart from having a high speed also mimics IC behavior in Silicon. An analog/digital circuit simulator PSpice is used for the purpose. The advantage of SPICE is that it offers models that accurately define a CMOS process. Since, SPICE simu...

The phase frequency detector has been designed for high frequency phase locked loop in 180 nm CMOS Technology with 1.8V supply voltage using CADENCE Spectre tool. A Virtuoso Analog Design Environment and Virtuoso LayoutXL tools of Cadence have used to design and simulate schematic and layout of phase frequency detector respectively. Architecture of phase frequency detector (PFD) has simulated t...

This study introduces a reversible optical fulladder. Also optical NOT and NOR gates are implemented through Electro-Absorption-Modulator / Photo Detector (EAM/PD) pairs, were utilized for fulfilling reversible R gate. Then, reversible fulladder was designed based on the proposed reversible optical R gate. The operation of the suggested fulladder was simulated using Optispice and it was fou...

Partial discharge (PD) pattern classification has recently become popular since the automated acquisition of PD signals has become vital and cogent. A novel method for identification of defects due to partial discharge is described in this paper. Starting from different PD families of specimen, several sets of characteristic vectors are determined and then used as input variables to the propose...

This paper presents a PAM-4 receiver (RX) for CMOS image sensor (CIS) link. A robust baud-rate phase detector (PD) is proposed, which alleviates the dead zone issue encountered in conventional sign-sign Mueller-Muller (SS-MM) PD when combined with an adaptive decision feedback equalizer (DFE). An optimum and unique locking point reached by using minimum mean squared error (SS-MMSE) biased state...
