摘要： An electronic envelope detection circuit includes an input signal detecting circuit having at least one MOS transistor configured to receive a radiofrequency input signal and to deliver an internal signal on the basis of the input signal. The biasing point of the at least one transistor is controlled by the input signal and a control signal. A processing circuit that is coupled to the input signal detecting circuit is configured to deliver a low-frequency output signal on the basis of the internal signal and further deliver the control signal on the basis of the output signal. In operation, the value of the control signal decreases when the average power of the input signal increases, and vice versa.

摘要： A radiofrequency (RF) amplifier includes an input terminal, an output terminal, and a power supply and biasing stage having an output coupled to the input terminal. An amplification stage of the RF amplifier includes a first transistor having a control terminal coupled to the input terminal and a first conduction terminal coupled to the output terminal. The power supply and biasing stage is configured to generate a bias voltage at the control terminal of the first transistor to simultaneously regulate a power supply voltage of the amplification stage to a first voltage and a bias current of the amplification stage to a first current.

摘要： A low-dropout regulator includes a power stage having an output terminal coupled to a load circuit operable in different operating modes in which it receives different output currents. An error amplifier has a first input coupled to a reference voltage and an output coupled to an input terminal of the power stage. A compensation circuit includes a first stage with an RC filter coupled to the input terminal of the power stage, and generating an initial compensation voltage. A second stage includes a first transistor coupled between a supply voltage and a second node, and controlled by a complementary control signal, a high-side capacitor coupled between the second node and ground, and a third transistor coupled between the initial compensation voltage and the second node, and controlled by a control signal representative of the current operating mode of the load circuit.

摘要： An amplifier includes at least two amplification stages coupled in parallel. Each amplification stage includes at differential pair of amplifying MOS transistors having gates connected to a first and second input nodes common to amplifying stages, and bulk regions connected to each other but insulated from bulk regions of the amplifying MOS transistors of the other amplification stages. A configuration circuit generates bias voltage for application to the bulk terminals in each amplification stage to set the threshold voltages of the amplifying MOS transistors, and thus configuring the operating range of each amplification stage so that different amplification stages have different operating ranges.
