 Abstract
In this paper, new automatic LC calibrator is proposed for realizing a passive LC filter with almost constant frequency characteristic regardless of the PVT variations. The SAW-less GPS RX front-end is implemented using a 65nm CMOS process using the proposed LC calibrator. Also, new dual-mode low noise amplifier (LNA) structure is proposed to generate the RF signal required for the LC calibrator. The characteristics of the implemented GPS RX front-end show the voltage gain of about 42.5 dB, noise figure of below 1.35 dB, the blocker input P1dB of -24 dBm in case of the worst blocker signal at 1710 MHz frequency, while it consumes 7 mA current at 1.2 V power supply voltage.
