| 摘 要： | 设计了一种全集成CMOS数字电视调谐器(DTV tuner)射频前端电路.该电路采用二次变频低中频结构,集成了低噪声放大器、上变频混频器、下变频混频器等模块.芯片采用0.18μm CMOS工艺实现,测试结果表明,在50～860MHz频率范围内,射频前端能够实现很好的输入阻抗匹配,并且总的增益变化范围达到20dB.其中,在最大增益模式下,电压增益为+33dB,单边带噪声系数(SSB NF)为9.6dB,输入参考三阶交调点(ⅡP3)为-11Bm;在最小增益模式下,电压增益为+14dB,单边带噪声系数为28dB,输入参考三阶交调点为+8dBm.射频前端电路面积为1.04mm×0.98mm,工作电压为1.8V,消耗电流为30mA.

| Abstract: | An RF front-end circuit for a fully integrated CMOS DTV tuner is presented in this paper,where double-conversion low IF architecture is employed.The chip is implemented in a 0.18μm CMOS process,which includes a wideband low noise amplifier,and upconversion and downconversion mixers.The measurement results show the front-end has good input matching and a 20dB variable gain range.In the maximum gain mode,the gain is +33dB,the single sideband noise figure (SSB NF) is 9.6dB,and the input referred third-order intercept point (IIP3) is -6dBm;In the minimum gain mode,the gain is +14dB,the SSB NF is 28dB,and the IIP3 is +8dBm.The RF front-end drains 30mA current from a 1.8V supply and the die area is about 1.04mm×0.98mm. |
