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 1.9mm 2 fabricated in a 65nm CMOS process without RF options and requires 25mA f...
