Wearable real-time Electrocardiogram (ECG) monitoring is an emerging wireless technology enabling early diagnosis and increased ability of prevention of cardiovascular diseases. However, the ECG signal suffers from Powerline Interference (PLI) which corrupts the biomedical recordings. Low power and high speed filtering of the ECG signal is essential to make the monitoring device portable. This paper...
At nanometer technology nodes, variability is a major roadblock for circuit performance. This has made timing estimation of circuits a tedious task. Effective Current Source Model (ECSM) characterization of standard cells has been evolved to solve this issue. In this paper, an analytical Threshold Crossing Point (TCP) model for a two stage buffer is derived. Proposed model relates TCPs with the input...
As scan compression matures, the focus is changing from delivering QoR to other pressing requirements like hierarchical DFT implementation, pin-limited test and enabling high speed shifting of scan chains. Combinational compression schemes have had great success in the last decade in delivering a solution that provided a fast transition from traditional scan based test to compression based test. In...
In this paper, a new methodology for analysis of SSO effect on jitter value based on IBIS v5.0 is proposed. Subsequently, investigation of the impact of simultaneous switching output (SSO) noise, jitter and timing closure of a complete 8 bit LPDDR2 bus at 400 MHz obtained using this developed methodology is presented. Experimental results obtained on automotive microcontrollers using the developed...
Real-time embedded applications span a wide range of domains including automotive and flight control systems, monitoring systems, multimedia systems, virtual reality, interactive gaming, robotics, telecommunications, etc. A late response in these systems might cause a wrong behavior which could possibly even lead to a critical system failure. A typical example is an anti-lock braking system in a car...
Efficient routing and cross-contamination minimization are two interrelated challenging areas in Digital Microfluidic Biochip (DMFB). This paper proposes a two phase heuristic technique for routing droplets on a two-dimensional DMFB. Initially it attempts to route maximum number of nets in a concurrent fashion depending on the evaluated value of a proposed function named Interfering Index (IInet)...
