Penerapan Metode Monte-Carlo untuk Analisis Toleransi Perubahan Nilai Komponen Terhadap Kinerja Osilator Frekuensi 2,3 GHz
Abstract: In
telecommunications equipment, an oscillator has a function to generate a
carrier signal. As the carrier signal, a high stability performance is
required. The frequency shift caused by component tolerances. In this research,
a Monte-Carlo method was used to analyze a component tolerance on the
performance of the oscillator at a frequency 2.3 GHz. A simulation was
performed by software Advance Design System (ADS). In this research, the
iterations were carried out as many as 212 times with tolerance component
values by 10%. The analyzed performance consists of a fundamental frequency
shift, a phase noise, the value of power fundamental, and a harmonic power.
Meanwhile, the oscillator has a structure of bias BJT common base-bias BFR183
with Vcc = 20 V, Vce = 8.2 V and Ic = 15 mA and a dielectric resonator as a
resonator. The oscillator has a fundamental frequency 2.3 GHz, phase noise
-135.6 dBc / Hz, power fundamental 10.8 dBm, and harmonic power -11.2 dBm. The
simulation results showed that the oscillator has a good performance with a
high degree of stability on a fundamental frequency by 73%, stability phase
noise 100%, stability power fundamental 64%, and stability harmonic power 61%.
This simulation has a confidence level of 95.4%, an error ± 3%, and the
estimation accuracy 95%.
