| Summary: | 碩士 === 國立交通大學 === 電信工程系所 === 96 === In this thesis, we propose two novel pulse generators for Impulse Radio Ultra-Wideband (IR-UWB) system. The adjustable pulse generators are realized by using two different skills. The first pulse generator is fabricated on PCB utilizing lump elements. On the other hand, the second pulse generator is simulated with TSMC 0.18μm CMOS technology.
The adjustable amplitude range, symmetry and low ringing of the monocycle pulse are important to judge the performance of the pulse generator. Furthermore, the pulse generator should avoid the process variation and be suitable for different requirements. In this thesis, we propose two pulse generators whose pulse amplitude is adjustable. These pulse generators use the second-order transient circuit at over-damping mode to generate the adjustable monocycle pulse with good symmetry and low ringing in the simulation and measurement.
