ABSTRACT:
A clocked comparator having an input differential amplifier, a sample and hold circuit, and a load stage. The load stage including a first transistor whose channel is connected between a first terminal and a first node, a second transistor whose channel is connected between a second terminal and a second node, a third transistor whose channel is connected between the first node, a third terminal and a fourth transistor whose channel is connected between the second node and the third terminal and a switch between the first and the second terminal. The gates of the first and the fourth transistor are connected to the first terminal. The gates of the second and the third transistor are connected to the second terminal. When the switch is closed the first and the second transistor form a positive differential impedance between the first and the second terminal. When the switch is open the cross-coupled third and fourth transistors form a negative differential impedance between the first and the second terminal.
