Abstract :
This paper introduces an ultra-wideband (UWB) system and its integrated circuit design for biotelemetry in-vivo wireless endoscope application that enables real-time diagnosis with high resolution images. The implemented UWB transmitter (Tx)/receiver (Rx) pair is a non-coherent differential transmit-reference (DTR) architecture. All-digital pulse generator (PG) Tx, and merged radio frequency (RF) Rx frond end including the low noise amplifier (LNA), mixer and low-pass filter (LPF) have been implemented along with the analog baseband using a 0.18um digital CMOS process. The PG operates at 200 Mbps at an ultra low 27 pJ/bit transmit energy.
