摘要：

针对数字电视射频接收机越来越宽的覆盖范围,更低的噪声系数要求以及更高的线性度,提出一种可用于UV频段数字电视射频接收的数字控制增益可配置的射频宽带放大器电路,引入噪声消除技术减少噪声系数,采用线性度改进技术提高中间电路的线性度,利用改进的源级跟随器结构实现更低的步进精度.电路采用0.18 um CMOS 工艺,1.8 V供电电源,在170~870 MHz频率信号输入下,可以实现最低3.8 dB的噪声系数,最大增益下提供-12 dBm的三阶交调点,55 dB的动态范围,步进精度为0.8 dB,消耗14.76 mW的功耗,面积为800 um×600 um.测试结果表明所设计的射频宽带放大器,相比传统的设计,在覆盖UV频段的同时能够提供更低的噪声系数,且提供更高的线性度.
Abstract:

To solve the problem that the tuner bandwidth is wider, a digital programmable RF wideband amplifier for UV-band digital (DTV) tuner is proposed in this paper to achieve a lower noise figure and improve the linearity of the circuit. The noise canceling technology is introduced to reduce the noise figure. The linearity improvement techniques are introduced to improve the linearity of the intermediate circuit and the source-level follower structure is improved to achieve more precise step accuracy are introduced. The circuit is fabricated in 0.18 um CMOS process. Under 1.8 V power supply and 170~870 MHz frequency signal input, the circuit achieves a 3.8 dB noise figure. The circuit can provide -12 dBm third-order intercept points when the gain is set to maximum. The circuit shows a 55 dB gain control range by 0.8 dB each step. The overall power consumption is less than 14.76 mW, and the die area is 800 um*600 um. The testing result shows that the noise figure is reduced as compared with the circuit mentioned before, while extend the bandwidth to UV band, and the linearity is improved as well．
