It is not easy to meet Time-to-Market pressure without proper assisting tools. However, a feasible emulation solution doesn’t exist to help the verification of AMS circuits. In order to change such condition, we try to develop a reliable emulating process based on the wave digital filter (WDF), which is a fast and accurate method to convert analog circuits into digital circuits. This method tries to represent the circuit characteristics by incident and reflected waves. In other words, it can transform an analog circuit containing continuous signal into equivalent digital circuit containing discrete signal. Although classical Wave Digital Filter (WDF) theory [1] was proven as a solid approach to emulate analog circuits, how to construct a correct WDF structure to support various circuits with complicated topology is still a problem. In this paper, a new Joined type (J-type) adaptor is proposed to solve the loop issue in WDF structures, which is the bottleneck of emulating complicated analog circuits. By inserting Joined type adaptors at proper circuit nodes to break the loop structure, the remaining WDF structure can still be built by a simple binary tree as in previous papers. As verified with several examples, the proposed approach is indeed a feasible solution to support various circuit types in WDF-based analog emulators. 劉建男 2017 學位論文 ; thesis 66 en_US |
