Abstract :
This paper introduces a differential transmit reference (DTR) ultra-wideband (UWB) receiver with four receiving antenna arrays for high data rate wireless endoscope applications for real-time transmission of high resolution images. The proposed architecture with an envelope detection scheme is presented and comprehensive system simulation results are used to analyze the receiver performance and derive the optimum specifications for a fully integrated CMOS implementation. System considerations for in-vivo applications including link budget analysis and safety issues also are introduced.
