Abstract

This paper presents the integrated circuit design of an ultra-wideband (UWB) transceiver for a wireless endoscope that enables real-time diagnosis with high resolution images. The implemented UWB transceiver is a non-coherent transmit reference (TR) architecture with differential binary phase shift keying (DBPSK) modulation. All-digital pulse generator (PG) and merged radio frequency (RF) front end including low-noise amplifier (LNA), mixer and low-pass filter (LPF) have been proposed and implemented along with the analog baseband and LC-voltage controlled oscillator (VCO) using 0.18 mum digital CMOS process.
