Abstract
To get a realistic filter design, one has to verify the temporary results against: element value variation (coming from Ambiental changes, aging or design errors) and imperfections of the built-in components. The first goal is achieved below by Monte Carlo simulation of the circuit with a given maximum tolerance value, while for the second, a simplified macromodel of the transconductor is used and the output capacitance varied. To complete the study, we are trying to answer to the question of selection of the filter architecture among parallel, cascade, and LC-to-Gm-C paradigms. Criterions will include the complexity of the circuit and the spread of the element values. To all that one may add questions related to the choice of the nominal transconductance since it may seriously affect the complete design and the noise properties of the architectures. Thorough analyses brought us to a conclusion that when all aspects are introduced one may rely first on the cascade solution as will be shown by a synthesis of 10 MHz passband width two-phase Gm-C filter.
