Novel current-conveyor-based single-resistance-controlled/voltage-controlled oscillator employing grounded resistors and capacitors

摘要

A novel single-resistance-controlled/voltage-controlled oscillator using three current conveyors, two grounded capacitors and three grounded resistors is presented. The proposed circuit offers the following advantageous features: employment of three grounded resistors for ease of adjustment, independent oscillation control through a single grounded resistor, independent frequency control through a single grounded resistor, employment of two grounded capacitors ideal for integration, ease of convertibility into a voltage-controlled oscillator, and very good frequency stability.
