Single-resistance-controlled/voltage-controlled oscillator using current conveyors and grounded capacitors

摘要

A new single-resistance-controlled/voltage-controlled sinusoidal oscillator using two current conveyors (CCs), two grounded capacitors and three grounded resistors is presented. This oscillator provides the following advantages: (i) independently controllable oscillation frequency and condition by grounded resistors, (ii) easy conversion into a voltage-controlled oscillator, (iii) all the passive components which are suitable for IC implementation are grounded, (iv) very good frequency stability. Experimental results that confirm the theoretical analysis are obtained.
