ABSTRACT:
A gain controllable wide-band low noise amplifier includes a first transistor coupled to an input node and an output node and amplifying an input signal to generate an output signal, a second transistor allowing the output signal to feedback to the input node, and a control circuit complementarily controlling transconductance of the first and second transistors.
