Abstract :
This paper presents a sinusoidal Wien-bridge ring and relaxation wide range voltage controlled oscillators. All described oscillators have potential using in different application, e.g. phase locked loops, modulation and detection. The frequency changing is based on optically coupled resistor with 100 dB dynamic range. The oscillators were constructed and measured.
