LEVEL SHIFTER CIRCUIT GENERATING BIPOLAR CLOCK SIGNALS

In some examples, a level shifter circuit comprises: a first transistor pair cascoded at a first input node; a second transistor pair cascoded at a second input node, wherein the first and transistor pairs couple at a first node, a second node, a third node, and a fourth node; a third transistor pair coupled to the first transistor pair at the first and the third nodes, wherein the third transistor pair is configured to generate a first bipolar clock signal; a fourth transistor pair coupled to the second transistor pair at the second and the fourth nodes, wherein the fourth transistor pair is configured to generate a second bipolar clock signal; and a clock generation circuit coupled to the first node, the second node, the third node, and the fourth node.
