Low weight data encoding for minimal power delivery impact

An electronic system, comprising:

• a power supply;
• an active circuit including a plurality of I/O cells which serve as switching transistors;
• and
• a power delivery system arranged to deliver a transient current from the power supply to the I/O cells of the active circuit, via an I/O bus, said power delivery system comprising a low weight encoding circuit arranged to encode data bits sent out on the I/O bus such that minimal current drawn is achieved to minimize signal and timing distortions.

A method of encoding data in a power delivery system, comprising:

• determining whether a predetermined number of data bits is current balanced;
• if said predetermined number of data bits is current balanced, driving said predetermined number of data bits onto an I/O bus;
• and
• if said predetermined number of data bits is not current balanced, encoding said predetermined number of data bits to ensure that said predetermined number of data bits is current balanced prior to being driven onto the I/O bus along with corresponding decode bits as to minimize signal and timing distortions.
