In the auditory pathway, the inferior colliculus (IC) is a major center for temporal and spectral integration of auditory information. There are widespread neural interactions in unilateral (one) IC and between bilateral (two) ICs that could modulate auditory signal processing such as the amplitude and frequency selectivity of IC neurons. These neural interactions are either inhibitory or excit...

This paper describes a doubly balanced Gilbert Cell mixer designed in BJT and CMOS technology to operate within 0 to 5 V. A 100 mv input signal was applied at both RF and LO port at different frequencies and their simulation curves were studied for a multiplier. The design done in BJT was taped out for fabrication and the chip on its return from foundry, was tested for its results. A comparison...

A CAD framework for embedded system design requires many different tools including software compilers, assemblers, and instruction-level simulators, and HDL compilers and simulators. In addition, tools for hardware/software partitioning and co-simulation are required. In this tutorial, we will describe state-of-the-art techniques for embedded system design. We will focus primarily on the Digita...

SystemC supports a wide range of Models of Computation (MoC) and is very well suited for the design and refinement of HW/SW-systems from functional downto register transfer level. However, for a broad range of applications the digital parts and algorithms interact with analog parts and the continuous-time environment. Due to the complexity of this interactions and the dominance of the analog pa...

 1971-73 Technical Officer I, Electronic Corporation of India Limited, India. Responsible for the board-level design of nonlinear functions used in analog computers. Contributed to discrete transistor implementations of operational amplifiers. Developed a folding technique (with digital logic) for multipliers that results in a more compact implementation. Recently (1999) applied for a provisio...

The action of β-secretase (BACE1) is strongly correlated with the onset of Alzheimer's disease (AD). Aminochalcone derivatives were examined for their ability to inhibit BACE1. Parent aminochalcones showed two digit micromolar IC(50)s against BACE1. Potency was enhanced 10-fold or more by introducing benzenesulfonyl derivatives to the amino group: 1 (IC(50) = 48.2 μM) versus 4a (IC(50) = 1.44 μ...

In this paper, an independent component analysis (ICA)-based disturbance separation scheme is proposed for statistical process monitoring. ICA is a novel statistical signal processing technique and has been widely applied in medical signal processing, audio signal processing, feature extraction and face recognition. However, there are still few applications of using ICA in process monitoring. I...

Verification of mixed signal system By G.Bonfini, M. Chiavacci, R. Mariani, E. Pescari YOGITECH SPA, via Lenin 132/p, 56017 San Martino Ulmiano (Pisa), Italia Electric and Electronic systems account for 49.2% of registered breakdowns (source: Allgemeiner Deutscher Automobil Club, 2003). Recent statistics on ICs said that 71% of System-on-Chip (SoC) re -spins are due to functional bugs, and 47% ...

One of the most important decisions that a backplane designer makes when defining system performance is the selection of the driver integrated circuit (IC) or IC input/output (I/O) technology. To achieve a high level of signal integrity, the physical backplane must be designed with specific signal behavior in mind. The physical backplane includes, but is not limited to, the number of loads, the...
