摘要:
In a receiver circuit for demodulating a high-frequency signal, a limiting amplifier stage with a downstream sigma-delta converter is connected in series with a mixer stage that transforms a high-frequency signal that is supplied at its input into an intermediate-frequency signal. The intermediate-frequency signal at the output of the limiting amplifier stage is value-discrete and time-continuous. The described receiver architecture has a high sensitivity, is substantially independent of production tolerances, and occupies a small area; therefore, it is particularly suitable for mobile radio applications.
