Abstract: A method for matching a pair of composite circuit elements (CEs) included in a circuit includes fabricating N CEs (e.g., resistors, transistors, current sources, capacitors) designed to match and switches configurable, according to M different combinations, to connect N/2 of the N CEs to form a first composite CE and to connect a remaining N/2 of the N CEs to form a second composite CE. Sequentially in time, for each combination of the M combinations, the switches are configured to form the first and second composite CEs according to the combination and a characteristic of the circuit is measured that includes the formed first and second composite CEs. The characteristic indicates how well the formed composite CEs match. A final combination of the M combinations is chosen whose measured characteristic indicates a best match and the final combination is used to configure the switches to form the composite CEs.

Abstract: A distributed network system may include a shared communication bus that operates in accordance with a communication protocol and a plurality of devices coupled to the shared communication bus. The communication protocol may define periods of time and an order by which each of the plurality of devices actively transmit data on the shared communication bus such that only one of the plurality of devices actively transmits data on the shared communication bus at a time to a remaining number of the plurality of devices through the shared communication bus. When the remaining number of the plurality of devices are not actively transmitting data, the remaining number of the plurality of devices may receive data via the shared communication bus so that bi-directional communication is established among the plurality of devices on the shared communication bus.
