摘要
An amplifier circuit. In some embodiments, the amplifier circuit includes: a telescopic amplifier, and a common mode feedback amplifier. The telescopic amplifier has a first signal input, a second signal input, a first output, a second output, a common mode feedback input, a first pole-splitting capacitor, and a second pole-splitting capacitor. The common mode feedback amplifier has an output connected to the common mode feedback input of the telescopic amplifier. The first pole-splitting capacitor is connected between the common mode feedback input of the telescopic amplifier and the first output of the telescopic amplifier, and the second pole-splitting capacitor is connected between the common mode feedback input of the telescopic amplifier and the second output of the telescopic amplifier.
