Although a number of sinusoidal oscillators have been described in earlier literature which employ only a single current feedback op-amp (CFOA) to generate voltage-mode sinusoidal oscillations, any sinusoidal oscillator circuit, which can provide a current-mode output signal explicitly (ie from a high output impedance node) while using only a single CFOA, has not been reported till date. This letter describes two such circuits and demonstrates their practicability through experimental results based upon AD844 type IC CFOAs.
