Abstract
A low noise amplifier circuit including a front end voltage sensing and matching amplification circuit, a gain circuit and a combining circuit is disclosed. The front end voltage sensing and matching amplification circuit includes an input and two outputs and provides a matched signal at each output. The gain circuit includes two inputs, each input being respectively coupled to at least one of the two outputs of the front end voltage sensing and matching amplification circuit. The gain circuit further includes two outputs and an output signal is provided at each output of the gain circuit. The combining circuit combines the two output signals of the gain circuit. The combining circuit includes two inputs, each input is respectively coupled to at least one of the two outputs of the gain circuit. The combining circuit further includes an output providing a combined signal.
