One Active Element Based CMOS Compatible Voltage-Mode TOQSO

A third-order quadrature sinusoidal oscillator is proposed in this study which produces two voltage output signals. A versatile current-mode active device, namely a current follower differential input transconductance amplifier with two resistors and three grounded capacitors, is used to realize the circuit. The use of single active block makes the circuit compact and simpler. The industry standard tool PSPICE with 0.18 µm technology process parameters is used for validation of the circuit, and the results are obtained in equivalence with the theoretical analysis.
