Versatile CCII-based Universal Current-mode Biquadratic Filter
New versatile universal current-mode filter with three inputs and three outputs using three multiple-output second-generation current conveyors,two grounded resistors and two grounded capacitors is proposed.Either applications single-input threeoutput or three-input single-output can be realized in the same configuration.It is more versatile than the universal one with single input and three outputs or the universal one with three inputs and single output.Unlike the previous1y works,it is highly flexible and easy to design.In the operation of single-input threeoutput,the lowpass,bandpass and bandreject can be realized simultaneously while the highpass and allpass responses can be easily obtained by connecting appropriated output currents directly without using additional stages.In the operation of three-input single-output,the lowpass,bandpass,highpass,bandreject and allpass can be realized from the same configuration without any inverting-type current input signals or double input current signals.The proposed circuit maintains the following advantages:(i)the employment two grounded capacitors ideal for integrated circuit implementation,(ii)high output impedance good for cascadability for the current-mode circuits,(iii)no need to impose component choice,(iv)no need to employ inverting-type current input signals,and(v)low active and passive sensitivity performances.HSPICE simulations with TSMC 0.18μm 1P6M CMOS technology and ±0:9V supply voltages to verify the theoretical results.
