Özet

Carbon nanotube field-effect transistor (CNTFET) is a strong candidate to replace existing silicon-based transistors. The ballistic transport of electrons in the CNTFET channel leads to ultra-low-power and high-frequency devices. Although a lot of digital applications of CNTTFET were presented, less work was done in analog applications of CNTFETs. This paper presents analog applications of CNTFET and its implementation of voltage differencing transconductance amplifier (VDTA). The CNTFET VDTA based filters and oscillators were proposed. The VDTA circuits are resistorless and can be tuned electronically only by changing transconductance. The proposed CNTFET VDTA shows power consumption of 4000 times less than compared to silicon CMOS technology and a significant reduction in chip area. All simulations were performed using SPICE and MATLAB simulation tools.
