Abstract :
Concerns a dynamic range (DR) comparison of reciprocal state-space Gm-C biquad filters based on the adjoint transformation. A detailed analytical description of general Gm-C filters (of voltage- and current-mode) of arbitrary order is derived and discussed. Based on the earlier results of Groenewold [1992], the general DR formulas for both types of state-space Gm-C filters are given. Finally, a dynamic range comparison of selected second-order G m-C filters of both modes is performed
