Abstract
An amplifying circuit including a first gain circuit, a second gain circuit, a Miller capacitor, a positive feedback circuit and a feedforward gain circuit. The second gain circuit is configured to receive a first gain signal from the first gain circuit and generate a second gain signal. The Miller capacitor, the positive feedback circuit and the feedforward gain circuit are electrically coupled between an input terminal and an output terminal of the second gain circuit. The positive feedback circuit is configured to feedback the signal of the output terminal of the second gain circuit to the input terminal of the second gain circuit. The feedforward gain circuit is configured to amplify the first gain signal to output a third gain signal to the output terminal of the second gain circuit.
