Improved grounded-capacitor SRCO using only a single PFTFN

摘要

A new circuit configuration for the realization of a single-resistance-controlled Sinusoidal oscillator is presented which uses only one positive four terminal floating nullor (PFTFN) along with two grounded capacitors and five resistors and offers independent control of the frequency of oscillation as well as the condition of oscillation through separate resistors. Experimental results showing the workability of the proposed circuit have been given.
