Abstract

This research paper contains current mode first order filter structures using single current controlled differential difference current conveyor (CCDDCC) and passive components. It can implement both inverting and non-inverting low pass, high pass and all pass functions from the same topology. The gain of the both inverting and non-inverting filters can be electronically controlled with the help of intrinsic resistance at X-terminal of CCDDCC. Phase of all pass filter can be changed over the whole range (180° to -180°). The structures are simulated using PSPICE with TSMC 0.25μm CMOS process. Simulation results agree well with the theory.
