A 9-bit 33MHz Hybrid SAR Single-slope ADC

In this work a 9-bit, 33MHz hybrid SAR single-slope ADC for element-level digitization in 2D ultrasound transducer arrays is presented. This hybrid architecture consists of a 5-bit SAR ADC followed by a 4-bit single-slope ADC. In the comparator design, the dynamic comparator and the continuous-time comparator for the SAR and single-slope...

Receiver Windowing Design for Narrowband Interference Mitigation in MB-OFDM UWB System

In 2005, the WiMedia Alliance working with the European Computer Manufacturers Association (ECMA) announced the establishment of the WiMedia MB-OFDM (Multiband Orthogonal Frequency Division Multiplexing) UWB radio platform as their global UWB standard. It was also chosen as the physical layer (PHY) of high data rate wireless specifications for...
