  • Patent number: 10498228
    Abstract: A circuit that can rapidly and precisely change the state of any circuit with some form of memory, whether it is a voltage across a capacitor, a current in an inductor, a digital value, or otherwise, using cyclically swapped circuits. For the case of a value stored on a capacitor: By swapping extra capacitors with preemptively set voltages using electronic switches, inherent settling times and defects of real RC circuits can be replaced with electronic switching times and switch defects. This dramatically improves speed and performance and is applicable on many circuit types including faster acquisition sample and hold circuits, faster amplifier nulling circuits, and any circuit that requires rapidly changing the DC voltage stored on a capacitor, and any circuit that requires rapidly changing the state or a circuit that has memory.
