Circuit arrangement for generating a complex signal and the use of this circuit arrangement in a high-frequency transmitter or receiver

摘要

A circuit arrangement for generating an IQ signal which comprises an oscillator (3) and a frequency divider (4). The oscillator (3) and the frequency divider (4) are arranged in a common current path between the supply and reference potentials (7, 5) in accordance with the proposed principle. It is possible to operate the two function blocks using a common BIAS current and additionally to save components.
