Patent ID: 7368948

Claim:
An integrated receiver circuit, comprising: a first voltage converter including: a first input terminal for receiving an input signal; an output terminal for supplying a first converted input signal; and a source follower circuit that generates the first converted input signal with a level that is lower than a level of the input signal; a second voltage converter including: a first input terminal for receiving a reference signal, wherein the input signal oscillates about the reference signal; an output terminal for supplying a first converted reference signal; and a source follower circuit that generates the first converted reference signal with a level that is lower than a level of the reference signal; and an amplifier stage including: an output terminal for supplying an amplified signal having a level that depends on the level of the input signal with reference to the reference signal; a first differential amplifier circuit including a first input terminal for receiving the first converted input signal and a second input terminal for receiving the first converted reference signal; and a second differential amplifier circuit including a first input terminal for receiving the input signal and a second input terminal for receiving the reference signal; and a control stage comprising: an output terminal; a first transistor with a control terminal; a second transistor with a control terminal, the second transistor of the control stage being coupled to the output terminal of the control stage; and a third transistor with a control terminal, wherein: the first transistor of the control stage is coupled to the output terminal of the control stage; and wherein the control terminal of the third transistor of the control stage is actuated by one of the first converted reference signal and the reference signal.
