Abstract :
A general approach for the analysis of continuous-time Gm-C filters based on matrix descriptions is presented. Explicit formulas for the transfer function of any Gm-C filter structure and for the sensitivity functions are derived. Relationships between the passive network of the filter and its transfer function are presented. The considerations lead to a new, more general definition of state-space Gm-C filters. An example for the design of a Gm-C filter with floating capacitors is given.
