AN AHDL-BASED METHODOLOGY FOR COMPUTER-SIMULATION OF SWITCHED-CAPACITOR FILTERS

In this paper an AHDL-based method for computer simulation of switched -capacitor networks is described. It is based on the transformation of these circuits from the sampled-data domain to the continuous-time do main and on the description of the obtained network with a behavioural language. This approach uses a general-purpose circuit simulator to a nalyse accurately and efficiently a wide range of circuits in both the frequency and the time domain. Reduced computation time is also ensur ed. The performance and the advantages of this method are illustrated by presenting and discussing a number of simulation examples.
