Abstract
An amplifier includes an amplifying stage, a cascoded circuit, an input feed-forward circuit and an output stage. The amplifying stage is arranged receiving a differential input pair to generate an amplified differential input pair. The input feed-forward circuit is coupled to the cascoded circuit, and is arranged for feeding the differential input pair forward to the cascoded circuit. The output stage is coupled to the amplifying stage and the cascoded circuit, and is arranged for generating a differential output pair according to the amplified differential input pair and an output of the cascoded circuit.
