Öz

Bu makale, CMOS tabanlı VDCC (Voltage Differencing Current Conveyor) devreleri ile fark kuvvetlendiricisi FGMOS tabanlı VDCC devrelerinin karşılaştırmasını ve performans analizini sunar. VDCC devresinin giriş aşamasındaki fark kuvvetlendiricileri, CMOS yerine FGMOS kullanılarak tasarlanır. VDCC devresinin giriş katlarındaki fark kuvvetlendiricilerinin CMOS yerine FGMOS kullanılarak tasarlanması, devrenin giriş sinyalini yükselterek doğrusallık ve voltaj takip etme özelliklerinde önemli bir artış sağlar. Aynı zamanda FGMOS transistörler kullanılarak devrenin aritmetik hesaplamaları sağlayan giriş aşaması basitleştirilir. VDCC devre topolojisinin çok yönlülüğünü göstermek için üç girişli tek çıkışlı (TISO) tip bant geçiren filtre uygulaması verilir. CMOS tabanlı VDCC filtre devresinin THD değeri %15.99 olarak bulunur. Önerilen fark kuvvetlendiricisi FGMOS tabanlı VDCC filtre devresinin THD değeri %1.03 olarak bulunur. Teorik analiz sonuçları, simülasyon sonuçlarını doğrulamaktadır. Sunulan CMOS ve FGMOS tabanlı bant geçiren filtreler, 0.9 V'a eşit bir güç kaynağı voltajı olan VDD ile TSMC CMOS 0,18 μm teknolojisi kullanılarak simüle edilir. Önerilen devre

Comparison of Performance Analysis of CMOS-based VDCC and Differantial Amplifiers FGMOS-based VDCC Circuits and Its Filter Application

Öz

This paper presents a comparison and performance analysis of CMOS-based VDCC (Voltage Differencing Current Conveyor) circuits and differential amplifier FGMOS-based circuits. Differential amplifiers at the input stage of the VDCC circuit are designed using FGMOS instead of CMOS. Designing the differential amplifiers in the input stages of the VDCC circuit using FGMOS instead of CMOS amplifies the input signal of the circuit, providing a significant increase in linearity and voltage following properties. At the same time by using FGMOS transistors, the input stage of the circuit, which provides arithmetic calculations, is simplified. A three-input single output (TISO) type band-pass filter application is given to show the versatility of the VDCC circuit topology. The THD value of the CMOS-based VDCC filter circuit is found to be 15.99%. The THD value of the proposed differential amplifiers FGMOS-based VDCC filter circuit is found to be 1.03%. Theoretical analysis results confirm the simulation results. The presented CMOS and FGMOS-based band-pass filters are simulated using TSMC CMOS 0.18 μm technology with VDD, a power supply voltage equal to 0.9 V. The proposed circuit topology will be an essential reference in the literature for researchers to design new linearly tunable filters.
