摘要

CMOS技术在纳米尺度上面临着重大挑战。基于石墨烯的电子产品已经成为一种可行的、有望继续遵守摩尔定律的产品。本文提出了一种基于石墨烯场效应晶体管(GFET)逆变器的正型第二代电流输送器(CCII+)。提出了一种通用型电流型有源滤波器，采用CCII+作为有源元件，可以实现所有标准滤波器的功能。采用0.18um GFET技术，利用ADS工具对该GFET滤波器的性能进行了仿真分析。仿真结果表明，该滤波器在±0.5 V电源电压下，在10 MHz频率下功耗为1.2 mW。此外，所提出的滤波器的中心频率可以通过电子调谐。作为应用，给出了一个正交振荡器的实例。对基于GFET电流输送的第一种有源滤波器的性能与CMOS技术进行了比较。

A universal current-mode current conveyor filter based on GFET inverter

ABSTRACT CMOS technology faces significant challenges at the nanoscale. Graphene-based electronics has emerged as a feasible promising to continue obeying Moore’s law. In this paper, a positive-type second-generation current conveyor (CCII+) builds with Graphene FET (GFET) inverters is proposed. A universal current-mode active filter is presented which can realise all standard filter functions employing CCII+ as an active element. The performance of the GFET filter was simulated and analysed with 0.18um GFET technology using ADS tools. The simulation results demonstrate that the proposed GFET filter consumes 1.2 mW at 10 MHz with ±0.5 V supply voltage. Furthermore, the centre frequency of the proposed filter can be tuned electronically. As an application, a quadrature oscillator example is given. The performance of first active filter based on GFET Current conveyor is compared with CMOS technology.
