摘要：

This paper presents a systematic approach for the realization of resistorless wave active filter using voltage differencing transconductance amplifier. The proposed filter uses grounded capacitor and also possesses electronic tunability of cut-off frequency via bias current. The functionality of the proposed filter is verified for a 4th order low pass filter through PSPICE simulation using 0.18 A mu m TSMC CMOS technology parameter. Experimental results using commercially available IC LM13700/NS are also included which corroborate the theoretical and simulated results.
