Patent number: 9768743Abstract: A circuit includes a reference voltage circuit, a filter circuit configured to receive an output of the reference voltage circuit, and a voltage follower configured to receive an output of the filter circuit and generate a bias voltage. The filter circuit is configured to combine signals on a reference ground with the output of the reference voltage circuit. A method of providing a bias voltage includes generating a reference voltage using a reference voltage circuit, filtering the reference voltage to generate a second voltage using a filter circuit, and generating the bias voltage according to the second voltage using a voltage follower circuit. Filtering the reference voltage includes combining a fluctuation of the reference ground with the reference voltage.Type: GrantFiled: June 3, 2015Date of Patent: September 19, 2017Assignee: Marvell International Ltd.Inventors: Sai-Wang Tam, Philip Godoy, Ming He, Renaldi Winoto
