Abstract
The present invention relates to a receiving device and method for removing a mismatch in a wireless communication system, and to a low noise amplifier (LNA) therefor. According to the present invention, the receiving method for removing the mismatch comprises the steps of: distinguishing the type of input signal received through a wireless network; controlling such that a common bias is applied to transistors within a low noise amplifier, if said input signal is a wideband signal; and outputting a signal from which said mismatch has been removed, by using a current mirror mode in which current paths within said low noise amplifier are crossed.
