摘要：
A new electronically tunable quadrature oscillator is presented using a biquad band pass filter. The new band pass filter is designed using two dual X second-generation multi-output current conveyors (DX-MOCCIIs), two grounded capacitors, two grounded resistors and one NMOS transistor working in the triode region. It is used to design a four-phase voltage and three-phase current output quadrature oscillator simultaneously. The frequency of the oscillator can be tuned externally through the MOS gate voltage without affecting the condition of oscillation. The phase noise, frequency stability and nonideality analysis are given. The functionality of the oscillator circuit has been confirmed by SPICE simulation and also hardware realization using commercially available IC AD844.
