This thesis designs a Gaussian pulse generator by the method of up-conversion with for use as a front end transmitter unit of an UWB-IR. The baseband pulse is generated using the delay elements (CTBV technique) but having the carrier frequency sourced externally can offer the advantage such as higher tunability of the pulse shape and mitigate phase noise if the clock source is jitter-free. The architecture design is successful and the simulation results exhibit the expected rendering of the up-converted Gaussian pulse trajectory. The design is implemented in the 65nm CMOS process technology by TSMC. The thesis briefly describes the basic radar fundamentals that are influenced as part of the pulse tuning capability, such as the carrier frequency, bandwidth which affects the resolutions and penetration into lossy mediums of the target. The potential applications of the system are also described, such as in snow hydrology, biomedical applications, etc. The architecture is described with reasoning for taking a specific design approach, providing the necessary component dimensions that can help replicate the design by other interested users. The chip has arrived on at the facility on 7 June 2020, one week before the deadline for submission of this thesis dated 15 June 2020. Within this one week window period, the wire-bonding of the chip on the PCB, setting up of the types of equipment required for measurement has been conducted and attempt to get the successful results have been made, but no expected results have been obtained from the implemented chip. Due to the shortage of time, further investigation of the problems or re-analyzing the design for potential faults could not be made.
