February 24, 2015, ISSCC, San Francisco—Manar El-Chammas from Texas Instruments described a high linearity, high bandwidth data converter for communications systems. This design challenges the normal tradeoff of the two parameters, yet achieves over 90 dB dynamic range and 200 MHz bandwidth. The design uses a pipelined architecture with integrated track-and-hold. Other changes such a…
February 23, 2015, ISSCC, San Francisco—Jaehyuk Choi from Samsung Advanced Institute of Technology described a low-power, 15 fps image sensor for always-on mobile and wearable devices. The ability to run on minimal power opens many new applications for smart sensors beyond taking pictures on a mobile device. This image sensor has two operating modes; ultra-low…
February 23, 2015, ISSCC, San Francisco—Long Xu from Delft University described a current sensing ADC with +/- 30 V input common-mode input range. The likely applications include remote sensing, motor control, and current monitoring where weak differential signals are in a very high common-mode voltage setting. The basic technology is to have a load at…
