Abstract :
A front-end IC for a 1.1-V, VHF paging receiver has been developed. Using a novel low-noise, low-distortion amplifier, it achieves a high sensitivity of -130 dBm and a low intermodulation sensitivity of -20 dBm while consuming only 1.98 mW. A 2.93-dB noise figure and a +5.0-dBm third-order intercept point are achieved under 50-Ω matching
