According to the abstract* released by the U.S. Patent & Trademark Office: "Examples of this description provide for a circuit. In some examples, the circuit includes a resistive network, a least significant bit (LSB) capacitor selectively coupled via a switch to receive an analog input voltage or to a selected first tap in the resistive network, and a charge boost network coupled in parallel with the resistive network and to a midpoint of the resistive network. To determine a most significant bit of lower order bits...
