ABSTRACT:
A low-noise amplifier includes a first resistor that receives a first signal of a differential input signal, and a second resistor that receives a second signal of the differential input signal. The amplifier includes a first transconductance device coupled to the first resistor that provides a first signal of a differential output signal, and a second transconductance device coupled to the second resistor, that provides a second signal of the differential output signal. The receiver also includes a first capacitor coupled between the first resistor input and a control electrode on the second transconductance device, and a second capacitor coupled between the second resistor input and a control electrode on the first transconductance device. The low-noise amplifier can include additional gain stages.
