【摘要】：近年來(lái),快速發(fā)展的無(wú)線通信技術(shù)給人們生活帶來(lái)了巨大的變化。現(xiàn)有的多個(gè)無(wú)線通信標(biāo)準(zhǔn),包括針對(duì)廣域網(wǎng)的蜂窩移動(dòng)通信、針對(duì)局域網(wǎng)的無(wú)線局域網(wǎng),以及針對(duì)個(gè)域網(wǎng)的超寬帶通信等,可以覆蓋所有的應(yīng)用場(chǎng)景,實(shí)現(xiàn)隨時(shí)隨地的個(gè)人通信。多網(wǎng)長(zhǎng)期共存要求無(wú)線通信終端能同時(shí)兼容多個(gè)無(wú)線通信標(biāo)準(zhǔn)。目前為止,學(xué)術(shù)界和工業(yè)界已經(jīng)研究并開(kāi)發(fā)了兼容蜂窩移動(dòng)通信和無(wú)線局域網(wǎng)／全球定位系統(tǒng)的多標(biāo)準(zhǔn)射頻集成電路,頻率覆蓋范圍900.MHz～5.8.GHz.如果進(jìn)一步覆蓋短距離的超寬帶通信標(biāo)準(zhǔn),其覆蓋頻率范圍需要擴(kuò)展到11 GHz。因此,研究覆蓋更寬頻率范圍的寬帶射頻集成電路具有重要意義。在此背景下,本論文針對(duì)WCDMA/WLAN/OFDM-UWB多標(biāo)準(zhǔn)兼容系統(tǒng),開(kāi)展了0.1-GHz～11-GHz寬帶CMOS射頻接收器關(guān)鍵電路的設(shè)計(jì)研究。研究重點(diǎn)是寬帶低噪聲放大器和寬帶下變頻混頻器。本論文的主要貢獻(xiàn)體現(xiàn)在：1)提出了一種頻率范圍在0.5-GHz～10.6-GHz的電感反饋結(jié)構(gòu)差分低噪聲放大器。在反饋回路中引入的電感可以同時(shí)實(shí)現(xiàn)輸入阻抗匹配和高頻增益補(bǔ)償。不同于以往采用多個(gè)電感分別匹配輸入阻抗和補(bǔ)償高頻增益的方法,本論文的方案所用電感少,節(jié)省了芯片面積；2)設(shè)計(jì)并實(shí)驗(yàn)驗(yàn)證了后置有源巴倫的低噪聲放大器,在0.1-GHz～12-GHz范圍內(nèi)實(shí)現(xiàn)低噪聲放大和單端-差分轉(zhuǎn)換。相對(duì)于以往的前置有源巴倫方法,克服了輸入節(jié)點(diǎn)對(duì)地電容對(duì)寬帶輸入阻抗匹配的限制；3)提出并實(shí)驗(yàn)驗(yàn)證了一種帶有相位矯正網(wǎng)絡(luò)的有源巴倫-低噪聲放大器混合結(jié)構(gòu),相對(duì)于傳統(tǒng)的有源巴倫-低噪聲放大器混合結(jié)構(gòu),可以在更寬的信號(hào)頻率范圍內(nèi)(0.1-GHz～11-GHz)實(shí)現(xiàn)相位失配的矯正；4)提出并實(shí)驗(yàn)驗(yàn)證了一種寬帶吉爾伯特混頻器,在混頻器輸入管的柵極和漏極增加電感來(lái)拓展混頻器的帶寬,實(shí)現(xiàn)了0.1-GHz～11-GHz頻率范圍內(nèi)的輸入信號(hào)下變頻；5)提出并實(shí)驗(yàn)驗(yàn)證了一種帶有可調(diào)LC-R網(wǎng)絡(luò)的折疊式吉爾伯特混頻器,可以實(shí)現(xiàn)切換工作頻段和補(bǔ)償不同頻段增益；6)基于上述后置有源巴倫的低噪聲放大器和寬帶吉爾伯特混頻器,采用0.13-μm射頻CMOS工藝設(shè)計(jì)并實(shí)驗(yàn)驗(yàn)證了一款寬帶射頻接收器前端芯片。實(shí)測(cè)的最小噪聲系數(shù)為3.35 dB,最大增益為24 dB,最高三階交調(diào)點(diǎn)為-5.2 dBm7)基于上述混合結(jié)構(gòu)有源巴倫低噪聲放大器和帶有可調(diào)LC-R網(wǎng)絡(luò)的吉爾伯特混頻器,采用0.13-μm射頻CMOS工藝設(shè)計(jì)并實(shí)驗(yàn)驗(yàn)證了一款工作頻段可調(diào)射頻接收器前端芯片。實(shí)測(cè)的最小噪聲系數(shù)為3.2 dB,最大增益為29.6 dB,最高三階交調(diào)點(diǎn)為-4.2 dBm。
[Abstract]:In recent years, the rapid development of wireless communication technology has brought great changes to people's lives. Existing wireless communication standards, including cellular mobile communications for WAN, WLAN for LAN and UWB for personal area networks, can cover all application scenarios. Realize personal communication anytime, anywhere. Long-term coexistence of multi-networks requires that wireless communication terminals be compatible with multiple wireless communication standards simultaneously. So far, academia and industry have studied and developed multi-standard radio frequency integrated circuits compatible with cellular mobile communications and wireless local area networks / global positioning systems, with a frequency coverage of 900.MHz / 5.8GHz. If UWB communication standards are further covered at short distances, their frequency coverage will need to be extended to 11 GHz. Therefore, it is of great significance to study wideband RF integrated circuits with wider frequency range. In this context, the design and research of the key circuits of 0.1-GHz~11-GHz broadband CMOS RF receiver are carried out for WCDMA/WLAN/OFDM-UWB multi-standard compatible system. The research focuses on broadband low noise amplifier and broadband downconversion mixer. The main contributions of this thesis are as follows: 1) A differential low noise amplifier (LNA) with inductance feedback structure in the frequency range of 0.5-GHz~10.6-GHz is proposed. The inductance introduced in the feedback loop can realize input impedance matching and high frequency gain compensation simultaneously. Different from the previous methods of matching input impedance and compensating high frequency gain with multiple inductors, this paper uses less inductors and saves chip area. 2) the low noise amplifier of post-active Barron is designed and experimentally verified. The low noise amplifier and single-terminal differential converter are realized in the 0.1-GHz~12-GHz range. Compared with the previous pre-active Barron method, the limitation of input node to ground capacitance matching to wideband input impedance is overcome. 3) A hybrid structure of active Barron low noise amplifier with phase correction network is proposed and experimentally verified, compared with the traditional hybrid structure of active Barron low noise amplifier. The phase mismatch can be corrected in a wider signal frequency range (0.1-GHz~11-GHz). 4) A wideband Gilbert mixer is proposed and experimentally verified. The input signal in 0.1-GHz~11-GHz frequency range is realized by increasing the inductance in the gate and drain of the mixer to expand the frequency band of the mixer. 5) A foldable Gilbert mixer with adjustable LC-R network is proposed and experimentally verified, which can realize switching frequency band and compensating different frequency band gain. 6) based on the low-noise amplifier and the wide-band Gilbert mixer, an RF receiver front-end chip is designed and verified by using 0.13- 渭 m RF CMOS technology. The measured minimum noise coefficient is 3.35 dB, the maximum gain is 24 dB, the highest third-order intermodulation point is -5.2 dBm7) based on the hybrid structure active Baron low-noise amplifier and Gilbert mixer with adjustable LC-R network, An adjustable RF receiver front-end chip with operating frequency band is designed and verified by using 0.13- 渭 m RF CMOS technology. The measured minimum noise coefficient is 3.2 dB, the maximum gain is 29.6 dB, the highest third-order crossover point is -4.2 dBm..
