Amplifier device

Abstract

An amplifier device is provided. The amplifier device includes an inductor, a capacitor, an amplifier, a biasing circuit, and a driving circuit. The inductor and the capacitor are connected in series between a bias point and a first reference voltage terminal. The amplifier is coupled to the bias point to receive a bias signal. The biasing circuit generates a first benchmark voltage according to a bias reference signal and generates the bias signal at the bias point. The driving circuit includes a charging circuit and is coupled to the biasing circuit. The driving circuit controls the charging circuit according to the first benchmark voltage to provide a driving signal for charging the capacitor.
