Abstract:
An active cascode differential latch comprising:a first input port; a second input port; a first transistor of a first conductivity type comprising a gate, and a drain connected to the first input port; a second transistor of the first conductivity type comprising a gate, and a drain connected to the second input port; a first active cascode transistor of the first conductivity type comprising a source connected to the drain of the first transistor, and a gate connected to the gate of the first transistor; a second active cascode transistor of the first conductivity type comprising a source connected to the drain of the second transistor, and a gate connected to the gate of the second transistor; a load coupled to the first and second active cascode transistors; and a pre-charge transistor to provide a low impedance path between the gates of the first and second transistors only if ON.
