Abstract:
1. A differential switching circuit comprising: a first transistor coupled between a first output node and a common node; a second transistor coupled between a second output node and the common node; and a switching driver comprising a first driver configured to generate a first driving signal in response to an input data signal and configured to apply the first driving signal to a control electrode of the first transistor, and a second driver configured to generate a second driving signal in response to an inverted input data signal that is opposite in phase to the input data signal and configured to apply the second driving signal to a control electrode of the second transistor, so as to complementarily drive the first and second transistors in response to an input data signal, wherein each of the first and second drivers comprises: wherein a voltage level of at least one of the first and second driving signals is maintained so as to cause at least one of the first and second transistors to operate in a saturation region regardless of a voltage variation of at least one of the first and second output nodes when the at least one of the first and second transistors is turned on.
