Abstract
A low noise amplifier including an amplifier kernel circuit and a DC bias unit is provided. The amplifier kernel circuit is used for receiving a single input signal or a differential input signal so as to output a differential output signal. The DC bias unit is coupled to the amplifier kernel circuit, and is used for processing a signal source to generate the single input signal or the differential input signal according to its circuit configuration.
Claims19
A low noise amplifier, comprising:
- a amplifier kernel circuit, for receiving and processing a single input signal or a differential input signal by adopting a means of bulk-cross-coupling, so as to output a differential output signal;
- and
- a DC bias unit, coupled to the amplifier kernel circuit, for processing a signal source to generate the single input signal or the differential input signal according to a circuit configuration of the DC bias unit.
