AbstractThis dissertation presents a differential UWB chipset for communication and medical sensing. The key components are UWB impulse generators, LNA, correlator and energy detection circuit. A quenched-oscillation concept is used for low power UWB impulse generation, which makes the UWB transmitters adaptable for medical implants. Furthermore, this impulse generation approach can easily introduce tunability to different spectral allocations in the USA, Europe and Japan as well as a BPM function. At the receiver side, both correlation receiver and energy detection receiver are implemented. The correlation receiver combines a differential LNA, a four-quadrant true multiplier, a template impulse generator, low pass filters and a differential buffer on a single chip. By combining the impulse generator and the correlation receiver, a bistatic radar is constructed for contact-less breathing pattern detection, target surface estimation and sub-surface 3-D localization. The energy detection receiver utilizes a squaring circuit to collect the energy of the received impulses. Based on this energy detection receiver, short-distance data transmission with a speed up to 700 Mbit/s using OOK modulation can be realized. In addition, a monostatic radar concept is proposed. A rapid turn-around impulse generator/LNA module IC is successfully designed.dc.description.abstract
