This thesis presents an architecture for generating a higher-order derivative of a Gaussian pulse using up-conversion. The design, fabricated using TSMC 65nm process technology, employs CTBV (continuous-time variable bandwidth) or delay elements to shape the Gaussian pulse and control its temporal trajectory. The system provides six selectable pulse widths, and the higher-order derivative is achieved by upconverting the pulse to a higher frequency. The goal is to enable tunability in pulse shaping and integrate the system as part of a larger UWB-IR system, optimizing for high dynamic range and reduced phase noise. Simulation results confirm the expected performance of the design.
