CNTFET based class AB current conveyor II: Design, analysis and waveform generator applications

“…The source and drain regions are like the ones as in the conventional MOSFET; however, the channel has undoped CNTs. 14,15,24 The number of CNTs (N), CNT pitch (S), and diameter of CNTs (D CNT ) are important parameters to optimize the performance of a CNTFET. Due to the use of CNTs, a CNTFET outperforms the conventional MOSFETS significantly, in terms of drive capability, speed, packing density, and low power consumption.…”

“…The unique features of a CNTFET include its ballistic transport of charge carriers resulting in high mobility, large thermal conductivity, excellent electrostatic control, and high carrier transport. [13][14][15] All these advantages are attributed to the CNTs used in realizing a CNTFET. A CNTFET can be fabricated efficiently with the existing MOSFET fabrication infrastructure.…”

“…[16][17][18][19][20][21][22][23] Various analog signal processing blocks employing CNTs have been realized. These include CNTFET-based operational transconductance amplifier (OTA), 14,24 CNTFET-based multistage differential amplifier, 15 dual output CC 25 and so on. However, CNTFET-based circuitry too have many limitations, like CNTFET-based OTA suffers from lower BW issue, 24 CNTFET-based CC are unable to realize the ideal characteristics CCII 25 and CNTFET based OP-AMP suffers from poor gain BW.…”
