Abstract :
A modified gyrator capacitor network is used for 2D SC filter design. Filters with circularly symmetric response are used to illustrate the synthesis method. The obtained filters are parasitic insensitive, two-phase SC networks. In comparison with the design methods presented by Nishikawa et al. (1984) and Matsui et al. (1985) it is found that the 2D SC filters designed by analog network emulation are more effective with respect to the number of phases or opamps than those designed by digital filter emulation
