Original Abstract
The paper deals with a couple of circuits of current-mode sine-wave oscillators. Both circuits presented are implemented using positive second generation current conveyors (CCII+). The principle of the first one is based on a conventional Wien-bridge network. However, this implementation suffers from the use of a floating capacitor, which can be unacceptable in the case of integration on the chip. The above mentioned drawback is solved in the second variant by the slight modification of the Wien-bridge network, which consequently allows the use of all capacitors grounded. The modified circuit version was manufactured by mean of the so-called diamond transistors, which stand for CCII+ active building blocks. The circuit behavior has been experimentally verified and results measured are included in the paper.
