In this research paper, a simple clock wise and counter clock wise Schmitt trigger employing single four terminal floating nullor (FTFN) with two external resistors is presented. The proposed Schmitt trigger avails CMOS based FTFN and it is extended for the application as a square and triangular wave generator, by adding an external capacitor to it. In addition, the proposed waveform generator provides independent tunability of amplitude of square wave by implementing the passive resistors using MOS transistors which make the circuit to be integrated fully. Finally, the verification of the proposed design is verified using PSPICE to justify the theoretical analysis. Also, post layout simulation and the experimental verification using commercially available current feedback operational amplifier named as ICAD844 based implementation for FTFN are included to confirm the reliability of the circuit.read more
