High-input Impedance Tunable Voltage-mode Multifunction Biquadratic Filter Using All-grounded Passive Elements
This paper introduces a high-input impedance tunable voltage-mode multifunction biquadratic filter.The proposed biquadratic filter with single input and five outputs employing two active components and all grounded passive elements.The circuit is very simple,consisting of one single-output differential difference current conveyor(DDCC),one dual-output inverting second-generation current conveyor(ICCII),three grounded resistors and two grounded capacitors.The filter can realize highpass,bandpass and lowpass filtering responses,simultaneously.It is widely used in various parts such as communication,measurement,instrumentation and control system.The proposed circuit offers the following advantages:(i)using grounded capacitors attractive for integration and absorbing shunt parasitic capacitance,(ii)using grounded resistors at X terminal of DDCC/ICCII suitable for the variations of filter parameters and absorbing series parasitic resistances at X terminal of DDCC/ICCII,(iii)high input impedance good for cascadability,(iv)no need to change the filter topology,(v)no need to component-matching conditions,(vi)orthogonal tunable of the resonance angular frequency and quality factor,and(vii)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.
