    Abstract: Embodiments of the present invention relate to the field of power amplifiers, and provide a power amplifier, a power amplification method, and a power amplification control apparatus and method. The power amplifier includes n Doherty power amplification units connected in parallel and an n-way outphasing combiner, where n≥2 and n is an integer; each Doherty power amplification unit includes one input end and one output end; the n-way outphasing combiner includes n input ends and one output end; and the output ends of the Doherty power amplification units are separately connected to the input ends of the n-way outphasing combiner. In the present invention, by means of the power amplifier having this structure, high efficiency can be maintained within a larger input power changing range, thereby further reducing power consumption.

    Abstract: Amplifier circuits implemented with a buffer amplifier with a voltage gain substantially equal to one. In one example, a continuous-time amplifier is implemented by applying the input source across the input and the output terminals of the buffer amplifier. In another example, a discrete-time amplifier is implemented. During the sampling phase at least one input voltage is sampled, and during the transfer phase at least one capacitor is coupled across the input and the output terminals of a buffer amplifier to effectuate an amplification.

    Abstract: The invention relates to an integrated input/output interface for low and/or high voltage signals of the digital and/or analog type. It comprises essentially a power amplification circuit block (2) having at least one low voltage input (A) and at least one high voltage output (B), and a second amplification circuit block (3) including active power components and having a high voltage input connected to said high voltage output (B) and at least one low voltage output (D). A conventional circuit block (4) prevents a high voltage signal being input to (B) from propagating through the block (2), so that it only affects the block (3).
    This interface is implemented in mixed high voltage BCD technology.
