A Series of Novel Second-order Filters Based on Current Mode
Liang Rong-xin · Journal of Circuits and Systems · 2003
A novel synthesized circuit of second-order filters based on current mode is proposed. A series of novel second-order filters based on current mode, including low pass, high pass and band pass filters, can be synthesized by choosing proper circuit elements. The results of circuit design and sensitivity analysis show that the circuits proposed in this paper have low sensitivities and their gains can be controlled independently. The theoretical analyses have been verified by the result of computer simulations.
