Description:
The students have learned CMOS analog design intensively in a graduate CMOS-I course. The students have also been introduced to filter design and synthesis before. The purpose of this graduate-level course is to utilize these two backgrounds and help students design integrated analog filters such as Switched-Capacitor Filters, Active-RC filters, and Gm-C filters. The students will get full exposure to practical on-chip implementation of these filters with different design examples. In light of the high-Q requirements of tunable RF band-pass filters, recently a new class of RF integrated filter structure has been introduced which is called “N-Path filter”. There will be an introduction and implementation tutorial of this class of filters which is extensively gaining attention for use in RF receivers and has a high potential to grow. There will be several sets of homework and a design project in this course. Also, there will be several handouts and a separate well-prepared exclusive note for N-path filters.
