Amplification circuit

An amplification circuit comprising:

• a radio-frequency input terminal configured to receive a radio-frequency signal;
• a radio-frequency output terminal configured to output an amplified radio-frequency signal;
• a first amplification stage circuit comprising a first terminal coupled to the radio-frequency input terminal, a second terminal coupled to the radio-frequency output terminal, and a third terminal;
• a second amplification stage circuit comprising a first terminal coupled to the radio-frequency input terminal, a second terminal coupled to the radio-frequency output terminal, an internal node, and a third terminal coupled to the internal node;
• and
• a variable impedance path coupled to the internal node, and comprising a first terminal coupled to the third terminal of the first amplification stage circuit, and a second terminal coupled to the third terminal of the second amplification stage circuit;
• wherein the variable impedance path has a low impedance when the variable impedance path is enabled, and the variable impedance path has a high impedance and the internal node is a high impedance node when the variable impedance path is disabled.
