Abstract
An amplifier circuit has a multi-stage amplifier, a compensation capacitor, and compensation circuits. The multi-stage amplifier has amplifiers cascaded between an input port and an output port of the multi-stage amplifier. The amplifiers include at least a first-stage amplifier, a second-stage amplifier and a third-stage amplifier. The compensation capacitor is coupled between the output port of the multi-stage amplifier and an output port of the first-stage amplifier. The compensation circuits include a first compensation circuit and a second compensation circuit. The first compensation circuit is coupled to the output port of the first-stage amplifier. The second compensation circuit is coupled to an output port of the second-stage amplifier.
