Electronically tunable current-mode quadrature oscillator

There have been sustained efforts to update the existing knowledge on quadrature oscillators. In this direction, the paper presents an electronically tunable quadrature oscillator with voltage as well as high impedance current outputs, employing translinear conveyors and grounded capacitors. The circuit enjoys non-interactive and wide frequency tunability. A critical study of the proposed circuit is made which is supplemented by good results.
