Abstract
In this article, a sinusoidal oscillator, AM and FM signal generator based on translinear current conveyors is introduced. The frequency and amplitude of the proposed circuit can be controlled by the bias currents. When an input current is applied as an information signal to the first and the second CCCII+s (Current Controlled Current Conveyors), the network functions as an FM signal generator. Contrarily, an AM signal is obtained by employing such information signals applied to the third CCCII+. In addition, this network simultaneously produces two signals that are 90/spl deg/ different in phase resulting in quadrature sinusoidal signals. This circuit consists of three CCCII+s and two grounded capacitors where, without any external resistors, this circuit is then suitable for IC architecture. The PSPICE simulation results are depicted. The given results agree well with the theoretical anticipation where the power consumption is approximately 2.4 mW.
