Abstract
Apparatus and methods for broadband low noise amplifiers (LNAs) with integrated limiters and fast recovery time are provided. In certain embodiments, an LNA includes a radio frequency (RF) amplification circuit, a feedback resistor connected along a feedback path from an output to an input of the RF amplification circuit, an input limiting circuit connected along an RF signal path between an RF input terminal and the input to the RF amplification circuit, and an input bias circuit that provides an input bias voltage to the input of the RF amplification circuit through the input limiting circuit.
