Abstract:
1. A circuit comprising: a voltage-to-current converter that receives a first voltage and a second voltage and outputs a first current and a second current in accordance with a clock signal; a first self-gated cascode circuit that receives the first current and outputs a third current in accordance with the clock signal; a second self-gated cascode circuit that receives the second current and outputs a fourth current in accordance with the clock signal; and a latch circuit that receives the third current and the fourth current and establishes a third voltage and a fourth voltage representing a resolution of a comparison between the third current and the fourth current, wherein the first self-gated cascode circuit is conditionally shut off based on a level of the third voltage, and the second self-gated cascode circuit is conditionally shut off based on a level of the fourth voltage.
