Quasi-cyclic codes are renowned for their structural design and low-complexity shift register encoding. However, existing design techniques based on difference families have limited code size options due to algebraic constraints. We introduce in this paper a notation of extended difference family (EDF) and provide a systematic code design based on EDFs with(More)
An automatic RC time constant tuning scheme is proposed for high linearity continuous-time and active RC circuits in a low power consumption environment. Instead of changing the (in filters), the RC time constant is tuned by discretely varying the integration capacitors to preserve a high linearity. The auto-tuning circuit, consisting of an analog(More)
The IEEE 802.11b and Bluetooth standards are two of the major driving forces of the short-range wireless communications market. Their co-existence in both home and office environments, grows constantly. As a result, a highly integrated and power efficient radio for both standards becomes an essential component for electronic products. A dual-mode(More)
This work presents a configurable time-interleaved pipeline architecture as an efficient solution for the ADC design in high data rate multi-standard radios. The ADC is implemented in a 0.25m BiCMOS process as part of an integrated dual mode 802.11b/Bluetooth direct conversion receiver. Its structure can be configured to accommodate the different sampling(More)
Thrombosis is a leading cause of death and the development of effective and safe therapeutic agents for thrombotic diseases has been proven challenging. In this study, taking advantage of the transparency of larval zebrafish, we developed a larval zebrafish thrombosis model for drug screening and efficacy assessment. Zebrafish at 2 dpf (days post(More)
In this paper, an approach to map the Bluetooth and 802.11b standards specifications into an architecture and specifications for the building blocks of a dual-mode direct conversion receiver is proposed. The design procedure focuses on optimizing the performance in each operating mode while attaining an efficient dual-standard solution. The impact of the(More)
An efficient mixed-mode Gaussian frequency-shift keying (GFSK) demodulator with a frequency offset cancellation circuit is presented. The structure is suitable for a low-IF Bluetooth receiver and can also be applied to other receivers involving continuous phase shift keying (CPSK) signals. The demodulator implementation is robust to tolerate process(More)
