The proposed TDC not only can achieve high speed of operation, but also have low circuit complexity as compared with conventional approaches.   This thesis presents two different time-to-digital architectures; the first proposed architecture employs a two-level cascade-stage structure to achieve high timing resolution and wide sampling range at the same time. Simulation results show that the proposed TDC can be improved to 200MHz with 50ps resolution in 90nm CMOS process technology. The second proposed architecture employs multi-level cascade-stage structure with interpolator to improve timing resolution, and achieve low power consumption, Simulation results show that the proposed TDC can be improved to 200MHz with 25ps resolution in 0.18µm CMOS process technology. In addition, the proposed TDC can be implemented with standard cells, making it easily portable to different processes and very suitable for biomedical chip applications.
