Issue Date: | 2009 | Abstract: | This project examines various dynamic-element-matching algorithms to improve the performance of delta-sigma modulator’s multi-bit DAC due to non-idealities in circuit. Simulations at system level are performed to verify and compare the performance of those algorithms. Then one of the algorithms, data-weighted-averaging algorithm is discussed in detail and implemented at transistor-level in Cadence with the CSM018IC process. A new implementation approach for the DWA algorithm is developed and tested at circuit level. From the simulation, it is verified the designed DAC with DWA algorithm is workable at sampling frequency of 500MHz with satisfying improvement in performance compared to without DWA algorithm. | URI: | http://hdl.handle.net/10356/17945 | Schools: | School of Electrical and Electronic Engineering | Research Centres: | Centre for Integrated Circuits and Systems | Rights: | Nanyang Technological University | Fulltext Permission: | restricted | Fulltext Availability: | With Fulltext |
