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.

Self-biased amplifier for use with a low-power crystal oscillator

A crystal oscillator with a configuration that allows for reduction of power consumption includes a crystal element, a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a sixth transistor, a seventh transistor, an eighth transistor, a ninth transistor, a crystal element. The crystal element includes a first terminal coupled to a control terminal of the seventh transistor and a second terminal coupled to a first terminal of the seventh transistor. The second transistor includes a control terminal coupled to an output terminal of the crystal oscillator and a first terminal of the ninth transistor.
