Abstract:
1. A low-noise amplifier, comprising: a first resistor having a first terminal for receiving a first signal of a differential input signal, and a second terminal; a first transconductance device having a first electrode coupled to said second terminal of said first resistor, a second electrode for providing a first signal of a first differential output signal, and a control electrode; a first capacitor having a first terminal coupled to said first terminal of said first resistor, and a second terminal; a second resistor having a first terminal for receiving a second signal of said differential input signal, and a second terminal; a second transconductance device having a first electrode coupled to said second terminal of said second resistor, a second electrode for providing a second signal of said first differential output signal, and a control electrode coupled to said second terminal of said first capacitor; and a second capacitor having a first terminal coupled to said first terminal of said second resistor, and a second terminal coupled to said control electrode of said first transconductance device.
