Patent number: 7330074Abstract: A differential amplifier includes an input stage, an output stage, and a control unit. The input stage generates differential currents in response to a voltage difference between differential input signals. The output stage generates an output signal at an output node. The control unit is coupled between the input stage and the output stage and includes a floating current source comprised of a cascode load for biasing the output stage with a quiescent current. Such a cascode load increases DC gain of the differential amplifier.Type: GrantFiled: September 6, 2005Date of Patent: February 12, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: Jae-Sung Kang, Chang-Mi Park
