Abstract

A low noise amplifier and a chip. The amplifier includes a biasing circuit unit, a first amplifying circuit unit, a first adjusting unit, a first signal input, a second signal input and a first signal output; the biasing circuit unit includes a first voltage output and a second voltage output; the first amplifying circuit unit includes a first N-type transistor, a first P-type transistor, a first output capacitor, a second output capacitor, a first impedance and a second impedance; gates of first N-type and P-type transistors are connected to first voltage output and first signal input, and second voltage output and first signal input, respectively, via adjusting unit; source of first N-type transistor is connected to source of first P-type transistor and second signal input; drains of first N-type and P-type transistors are connected respectively to impedance, and to first signal output and second signal output via output capacitor.
