Abstract

High data rate applications are becoming more popular every day. A small die area and low power consumption filters are essential for RF front-end modules in order to achieve effective integration. This paper presents two small, on-chip bandpass filters (BPFs) for 5G mm-wave communication systems based on the second-generation current-controlled current conveyor (CCCII) using 32 nm carbon nanotube field-effect transistors (CNTFET). The whale optimization algorithm is used for optimizing the current cut-off frequency and port X parasitic resistance (R_X) of the designed CCCII. The first filter is designed for the 5G n258 band, with a center frequency of 24.25–27.5 GHz, and the second one is designed for the 5G n260 band, with a center frequency of 37–40 GHz. The novelty of these CNTFET-based filters is that they are the first active filters, operating at the Ka-band frequency with low power consumption and a tiny size.

5G毫米波通信系统中基于优化碳纳米管场效应晶体管电流输送的ka波段带通滤波器

高数据速率应用程序每天都变得越来越流行。小的芯片面积和低功耗滤波器是射频前端模块实现有效集成的必要条件。本文提出了两种用于5G毫米波通信系统的小型片上带通滤波器（bpf），该滤波器基于32纳米碳纳米管场效应晶体管（CNTFET）的第二代电流控制电流输送机（CCCII）。采用鲸鱼优化算法对所设计的CCCII的电流截止频率和端口X寄生电阻（RX）进行优化。第一个滤波器设计用于5G n258频段，中心频率为24.25-27.5 GHz，第二个滤波器设计用于5G n260频段，中心频率为37-40 GHz。这些基于cntfet的滤波器的新颖之处在于它们是第一个有源滤波器，工作在ka波段频率，功耗低，尺寸小。

期刊介绍： Prediction through modelling forms the basis of engineering design. The computational power at the fingertips of the professional engineer is increasing enormously and techniques for computer simulation are changing rapidly. Engineers need models which relate to their design area and which are adaptable to new design concepts. They also need efficient and friendly ways of presenting, viewing and transmitting the data associated with their models. The International Journal of Numerical Modelling: Electronic Networks, Devices and Fields provides a communication vehicle for numerical modelling methods and data preparation methods associated with electrical and electronic circuits and fields. It concentrates on numerical modelling rather than abstract numerical mathematics. Contributions on numerical modelling will cover the entire subject of electrical and electronic engineering. They will range from electrical distribution networks to integrated circuits on VLSI design, and from static electric and magnetic fields through microwaves to optical design. They will also include the use of electrical networks as a modelling medium.
