Abstract
A differential amplifier is disclosed. The differential amplifier includes a first load element coupled between a first voltage and a first node. A second load element is coupled between the first voltage and a second node. A current source is coupled between a second voltage and a third node. A first input element is coupled between the first node and the third node and receives an input signal so as to adjust a voltage level of the first node. A second input element is coupled between the second node and the third node and receives a reference voltage signal so as to adjust a voltage level of the second node. A third input element is coupled between the second node and the third node and receives the input signal so as to adjust the voltage level of the second node.
