Single DD-DXCCII based quadrature oscillator with simultaneous current and voltage outputs

Abstract

In this paper, a versatile quadrature oscillator using single Differential Difference Second Generation Dual-X Current Conveyor (DD-DXCCII) as an active element, two grounded capacitors and three grounded resistors is presented. The proposed oscillator provides two current outputs and three voltage outputs in quadrature relationship simultaneously so named as versatile quadrature oscillator. The proposed versatile quadrature oscillator exhibits the feature of orthogonal control over the frequency of oscillation and condition of oscillation. Effects of non-idealities along with sensitivity analysis are also analyzed. The proposed circuit has low active and passive sensitivities. Parasitic study is further explored. The simulation results with 0.18μm CMOS process parameters using PSPICE are also given. Possible realization of proposed oscillator using AD-844 and LM13600 along with some simulation results are also given for completeness sake.
