This paper presents the circuit design and measured performance of a multi-band tuner for mobile TV applications. The tuner RFIC is composed of a wideband front-end, an analog baseband, a full integrated fractional- N synthesizer and an Iac digital interface. To meet the stringent adjacent channel rejection （ACR） requirements of mobile TV standards while keeping low power consumption and low cost, direct conversion architecture with a local AGC scheme is adopted in this design. Eighth-order elliptic active-RC filters with large stop band attenuation and a sharp transition band are chosen as the channel select filter to further improve the ACR preference. The chip is fabricated in a 0.35-#m SiGe BiCMOS technology and occupies a silicon area of 5.5 mm2. It draws 50 mA current from a 3.0 V power supply. In CMMB application, it achieves a sensitivity of-97 dBm with 1/2 coding QPSK signal input and over 40 dB ACR.

This paper presents an LC VCO with auto-amplitude control （AAC）, in which pMOS FETs are used,and the varactors are directly connected to ground to widen the linear range of Kvco. The AAC circuitry adds little noise to the VCO but provides it with robust performance over a wide temperature and carrier frequency *** VCO is fabricated in a chartered 50GHz 0.35μm SiGe BiCMOS process. The measurements show that it has - 127. 27dBc/Hz phase noise at 1MHz offset and a linear gain of 32.4MHz/V between 990MHz and *** whole circuit draws 6. 6mA current from 5V supply.

钢炮进化,不是新话题。然而,你不能忽略其群众基础的坚实度,更何况是被全球车迷顶礼膜拜的Golf以及老少皆宜、玩乐基因十足的Mini。“屌丝”的诱惑MRRacingGolfGTD在很多爱车人的潜意识里,一说起Golf,脑子里都会弹出“GTI”三个字母。而GTD对于很多人来说却是陌生的。同为高性能车型,小编我不禁要为GTD鸣个不平。没错,GTD 184匹的峰值马力与GTI的200匹的确有一定的距离,但是,别忘了,GTD 380Nm的峰值扭矩足足比GTI的280Nm高了100Nm。
