【摘要】：近年來,隨著無線通訊在便攜式產(chǎn)品與北斗導(dǎo)航中的應(yīng)用促使無線標(biāo)準(zhǔn)得到了空前的發(fā)展。由于人們?nèi)找嬖鲩L的需求,使得對無線通訊產(chǎn)品的要求逐步提高。對于之前的簡單實現(xiàn)單信號的處理已經(jīng)完全不能滿足人們的需求。相比之前,現(xiàn)在要求無線通信產(chǎn)品實現(xiàn)單芯片對多信號進行處理、要求更低的功耗、更小的面積,因此設(shè)計一款高集成、低功耗、高性能的無線射頻收發(fā)機芯片已經(jīng)成為目前研究重點。在無線通訊發(fā)展的過程中,CMOS工藝實現(xiàn)的成本效率極大的增強了多模式無線應(yīng)用的出現(xiàn)。現(xiàn)在多模/多頻帶接收機主要是基于復(fù)用的方案進行設(shè)計。它們避免使用多個芯片,并且能夠?qū)崿F(xiàn)可調(diào)諧,這使得它們在面積和功率消耗得到有效控制。對于多信號處理的接收機前端,模擬基帶濾波的設(shè)計是一個關(guān)鍵的任務(wù)。模擬濾波器主要是為了在多模接收機中進行信道的選擇,對有用信號不進行衰減或者說很小的衰減,對無用信號作很大的衰減,將有用信號從接收的信號中選擇出來。本論文主要研究基于TSMC0.18um工藝的可重構(gòu)帶寬濾波器。如何設(shè)計一款高線性、高抑制比與寬調(diào)諧范圍的濾波器逐步成為科研機構(gòu)的研究重點,因此來說,非常有必要對可重構(gòu)帶寬濾波器進行研究與設(shè)計。本論文主要是通過對濾波器的高線性與寬調(diào)諧范圍展開討論與設(shè)計。通過對濾波器的重要的組成單元跨導(dǎo)的線性度的分析與改進,從而來改變整體濾波器的線性度。并通過改進跨導(dǎo)單元的結(jié)構(gòu),實現(xiàn)寬的范圍的跨導(dǎo)調(diào)諧,使整個濾波器在0.65MHz至20MHz范圍可調(diào)。通過優(yōu)化整體電路的Q值,使整體電路的二倍頻衰減在整個可調(diào)范圍內(nèi)達到20dB/dec。對于電路和版圖都基于TSMC0.18um工藝完成,整體電路已經(jīng)投片。
[Abstract]:In recent years, with the application of wireless communication in portable products and Beidou navigation, wireless standards have been developed unprecedentedly. Due to the increasing demand of people, the demand for wireless communication products is raised gradually. For the simple implementation of single signal processing has been completely unable to meet the needs of people. Compared with the past, wireless communication products are required to process multiple signals on a single chip, requiring lower power consumption and smaller area, so a high integration and low power consumption is designed. High-performance RF transceiver chips have become the focus of research. In the development of wireless communication, the cost efficiency of CMOS technology greatly enhances the emergence of multi-mode wireless applications. The design of multimode / multi-band receiver is mainly based on multiplexing. They avoid the use of multiple chips and are tunable, which allows them to be effectively controlled in terms of area and power consumption. The design of analog baseband filter is a key task for the receiver front end of multi-signal processing. The main purpose of the analog filter is to select the channel in the multi-mode receiver. The useful signal is not attenuated or very small attenuation, and the useless signal is greatly attenuated, and the useful signal is selected from the received signal. In this paper, the reconfigurable bandwidth filter based on TSMC0.18um technology is studied. How to design a filter with high linearity, high rejection ratio and wide tuning range has gradually become the focus of research. Therefore, it is necessary to study and design the reconfigurable bandwidth filter. This paper mainly discusses and designs the high linear and wide tuning range of the filter. The linearity of the whole filter is changed by analyzing and improving the linearity of the important component unit of the filter. By improving the structure of the transconductance unit, a wide range of transconductance tuning is realized, which makes the whole filter adjustable from 0.65MHz to 20MHz. By optimizing the Q value of the whole circuit, the double frequency attenuation of the whole circuit can reach 20 dB / R in the whole adjustable range. For the circuit and layout are based on the TSMC0.18um process, the whole circuit has been cast.
