Abstract
A low-noise amplifier for a mobile communication terminal maintains linearity with the least current consumption. A low-noise amplifier controller detects a signal-to-noise ratio (SNR) of a received signal, and outputs a control signal of a preset voltage when the SNR is lower than a predetermined SNR even though AGC AMP controller increases the AGC gain according to field strength. A bias circuit increases a bias current according to the control signal output from the low-noise amplifier controller. A low-noise amplifier amplifies the received signal to a preset level according to the bias current provided from the bias circuit.
