Abstract: An amplifier includes a first transistor coupled to a first voltage source node and a second transistor coupled to a second voltage source node. The first and second transistors also couple together at an intermediate node. The amplifier further includes a third transistor coupled to the intermediate node and a fourth transistor coupled to the third transistor at a positive output node of the amplifier. Further, the amplifier includes a fifth transistor coupled to the intermediate node and a sixth transistor coupled to the fifth transistor at a negative output node of the amplifier.
