Patent number: 6836186Abstract: An AB class buffer amplifier controls quiescent current. The AB class buffer amplifier includes a first current controller and a second current controller. The first current controller sources current to an output node in response to a first logic level of a first signal, and buffers and outputs an input voltage to the output node in response to a second logic level of the first signal. The second current controller sinks the current from the output node in response to a second logic level of a second signal, and buffers and outputs the input voltage to the output node in response to a first logic level of the second signal. The first and second signals are generated at the first logic levels if the input voltage is higher than the output voltage and at the second logic level if the input voltage is lower than the output voltage.Type: GrantFiled: April 17, 2003Date of Patent: December 28, 2004Assignee: Samsung Electronics Co., Ltd.Inventors: Jae-youn Lee, Jun-seok Han
