Özet:

 


In
this work, a novel first order voltage-mode all-pass filter employing single
active element named current operational amplifier (COA), two resistors, one
capacitor and it’s application as sinusoidal oscillator is presented. The
resistors are implemented by using MOSFETs, so the resulting MOS-C circuit is
suitable for integration and the central frequency of the filter is
electronically tunable. Workability of the proposed filter and it’s application
is validated by PSPICE simulation software using TSMC 0.18 micron CMOS model
parameters. Simulation results are in good consistency with theoretical
analysis. The proposed circuit features precise frequency tuning, operability
at low voltage, low distortion and low phase error.
