چکیده انگلیسی
A new current-mode single-resistance-controlled-oscillator (SRCO) using two four-terminal-floating-nullors (FTFNs) is presented. The proposed SRCO provides the following advantageous features, not available simultaneously in any of the FTFN-based grounded-capacitor (GC) SRCOs known earlier so far: (i) use of two GCs which are attractive for IC implementation as well as eliminating/accommodating parasitic capacitances, (ii) very good frequency stability, (iii) low active and passive sensitivities, (iv) independent single grounded resistor control of oscillation frequency (as well as availability of such a control through a resistor ratio), (v) ready availability of explicit current-mode output, and above all, (vi) employment of a reduced number (only four) of resistors, in contrast to earlier two-FTFN-GC SRCOs requiring six resistors. Experimental results are included which confirm the practicability of the proposed circuit.
