摘要

GPS接收机前端采用增q电路实现了高动态输入范围。在移动电话环境中，LNA的Q会自动增加，将阻滞器性能提高11.3dB。该面积为1.9mm2，采用65nm CMOS工艺制造，无RF选项，需要来自1.3V电源的25mA，系统NF为1.5dB。

An L-band receiver-front-end-architecture using adaptive Q-enhancement techniques in 65nm CMOS as enabler for single-SAW GPS receivers

A GPS receiver front-end achieves high dynamic input range by using Q-enhancement circuitry. In mobile phone environments the Q of the LNA is automatically increased, improving blocker performance by 11.3dB. The area is 1.9mm2 fabricated in a 65nm CMOS process without RF options and requires 25mA from a 1.3V supply with a system NF of 1.5dB.
