Abstract
A self-biased amplifier includes a capacitor, a bias generation circuit and a common source amplifier. The capacitor is used to receive an input voltage and output an alternating component of the input voltage. The bias generation circuit is coupled to the capacitor, and used to generate a first bias voltage according to the alternating component. The common source amplifier is coupled to the bias generation circuit, and used to generate an amplified voltage according to the first bias voltage.
