Abstract: An evolvable circuit includes a plurality of reconfigurable switches, a plurality of transistors within a region of the circuit, the plurality of transistors having terminals, the plurality of transistors being coupled between a power source terminal and a power sink terminal so as to be capable of admitting power between the power source terminal and the power sink terminal, the plurality of transistors being coupled so that every transistor terminal to transistor terminal coupling within the region of the circuit comprises a reconfigurable switch.

Abstract: A process for efficiently computing moments in an interconnected circuit begins by partitioning the circuit into sets of line-like two-port circuits. Next, capacitors are converted to equivalent current sources and inductors are converted to equivalent voltage sources. From a first port, any connected voltage source which is present in line is added to the port voltage source. Then, that voltage source combined with the connected resistor and the Thevenin equivalent circuit is converted to a Norton equivalent circuit. The current source created from the conversion is added to a current source in the circuit and the Norton equivalent circuit is converted back to a Thevenin equivalent circuit. The process is recursively performed until the opposite port is reached. The moment is then computed from the final Thevenin equivalent circuit by using the voltage and current at the port. The Thevenin-Norton-Thevenin recursive process is then repeated for the opposite port.
