Abstract

The present invention relates to an operating point setting of an amplifier. Embodiments related to the setting of an operating point of an amplifier are described and depicted.

Description

Background technique [0001] Many communication systems are based on wireless transmission. The transceivers of these systems transmit and receive specific information and are coupled to antennas to convert electrical currents into electromagnetic waves and vice versa. The performance of a transceiver with respect to power consumption and transmitter linearity typically depends on the performance of an RF power amplifier. [0002] A radio frequency amplifier is a circuit for amplifying radio frequency signals so that they can be transmitted wirelessly via an antenna. The amplifier can have only a single amplification stage, or also a plurality of amplification stages. [0003] Radio frequency signals are typically generated by modulators that modulate a high frequency carrier signal with a baseband signal. The baseband signal represents the information to be conveyed in its non-shifted frequency spectrum. The characteristics of the carrier signal to be modulated may be ampl...
