  • Amplification circuit and reception chain
    Patent number: 9246456
    Abstract: An amplification circuit including: an input for receiving an input voltage; an output for exhibiting an output voltage; a primary amplifier configured to receive the input voltage from the input, receive a primary control voltage, first amplify the input voltage by a primary gain dependent on the control voltage, the output voltage corresponding to the first amplified input voltage, and supply the output voltage to the output; and a secondary amplifier configured to receive the input voltage from the input, second amplify the input voltage by a secondary gain, the primary control voltage corresponding to the second amplified input voltage, and supply the primary control voltage to the primary amplifier. The secondary amplifier has in operation an input admittance of at least 1 millisiemens.
