Grounded-capacitor SRCO using only one PFTFN

A new circuit configuration for the realisation of a single-resistance-controlled-sinusoidal oscillator (SRCO) is presented. The proposed circuit uses one positive four-terminal floating nullor (PFTFN), two grounded capacitors (GCs) along with four resistors; in contrast to previously reported single FTFN-based SRCOs which either require floating capacitors (FCs) also, or require at least five resistors when only two GCs are used. The workability of the proposed structure has been demonstrated by experimental results
