Abstract

An insensitive current-mode filter, implemented from two second generation current conveyors is introduced. The circuit uses four passive components and exhibits simultaneously two 2nd order transfer functions: highpass and bandpass. A versatile ASIC implementation is proposed for the circuit. It includes the filter core and three supplementary followers in order that the lowpass, bandreject and allpass will also be available. SPICE simulation results, which confirms the theoretical analysis, are reported and discussed the conveyors being implemented in a translinear form
