Özet

In this paper, a voltage summing current conveyor (VSCC) as an active building block for realizing the controlled oscillator and the summing amplifier applications has been presented. The VSCC required low supply voltage as +/- 0.5 V consumes low power and has a simple structure. The controlled oscillator has three passive components. The VSCC based oscillator offers using of the grounded capacitors which are suitable for IC implementation, using the less passive components, very good frequency stability and the low voltage operation. In addition, the summing amplifier has been realized using only one VSCC and a grounded passive resistor. The amplifier provides some advantages such as high accuracy and very high input impedance. The performance of the proposed circuit is simulated with SPICE to confirm the presented theory.
