Frequency compensated amplifier arrangement and method for operating a said frequency compensated amplifier arrangement

摘要

Frequency compensated amplifier arrangement, comprising– an initially - amplifier stage (v2) with an input and an output,– an output - amplifier stage (v1) with an input which is connected to the output of the initially - amplifier stage (v2) is connected, and with an output,– a modulator (mod1), which is at the input of the initially - amplifier stage (v2) is connected and the of the initially - amplifier stage (v2) a into a first and second clock phase supplies hacked useful signal,– a between the input and output of the output - amplifier stage (v1) connected to - and can be switched off first miller - compensation capacitor (c1), which during the first clock phase between the input and output of the output - amplifier stage (v1) can be switched electrically active, and– a between the input and output of the output - amplifier stage (v1) can be switched off to - and is connected to a second miller - compensation capacitor (c2) which, during the second clock phase between the input and output of the output - amplifier stage (v1) can be switched electrically active.
