DecaWave ScenSor Chip Incorporates TakeCharge ESD Protection from Sofics
Customized Approach Delivers Robust Protection, Reduced Development Costs; Low Capacitance and Leakage Support RF Transceiver IC’s High Performance
GISTEL, BELGIUM (February 22, 2012) – Dublin, Ireland-based DecaWave (www.decawave.com), the pioneering fabless semiconductor company specializing in ultra wideband (UWB) technology for Real Time Location Systems (RTLS) and Wireless Sensor Networks (WSN), is using TakeCharge® technology from Sofics® bvba of Belgium (www.sofics.com) to protect its new DW1000 RF transceiver chip from electrostatic discharge (ESD). Sofics is a leading provider of ESD solutions for ICs.
DW1000, the inaugural product in DecaWave’s ScenSor family of ICs, began sampling in November 2011. TakeCharge was chosen for its superior ESD protection, reduced development cost, low (100fF) capacitance for maximum circuit performance, and minimal (less than 100pA) leakage in nano-CMOS.
“The DW1000 is an ultra-wideband radio transceiver used in applications such as tracking patients in hospitals or locating stock in warehouses,” said William McFadden, VP Operations at DecaWave. “It needs robust protection against the ESD hazards it may encounter in these environments, without compromising its high-speed performance. “Sofics delivered a customized ESD solution in less than a week. The integration of the TakeCharge cell went so smoothly that we were able to release the chip for sampling within three weeks.” TakeCharge was also far more cost-effective than other approaches to ESD protection.

“Because TakeCharge technology is silicon and product-proven, our IP is available at a fraction of the shuttle cost incurred when designing a new cell,” said Sofics CEO Koen Verhaege. “In many cases we can deliver an off-the-shelf solution, or customize one for a specific IC and application, thus greatly reducing development costs and speeding time to market.

“TakeCharge cells also work right from the start, eliminating the need for re-spins, and take up less silicon real estate than comparable protection schemes. In DecaWave’s design the TakeCharge cell occupied only 3000um2 of chip space.” More information on TakeCharge is available from Sofics. Details of the ScenSor DW1000 are available from DecaWave.
