摘要： A circuit may include a transmitter for generating a signal indicative of input data, an on-chip channel for transmitting the signal from the transmitter, and a receiver comprising a receiving terminal that has a negative resistance value as input resistance of the receiving terminal, the receiver generating a signal indicative of recovered data based on the transmitted signal through the on-chip channel. The circuit may recycle a portion of charge stored in the on-chip channel using charge recycling, and the charge recycling is associated with the negative resistance value of the input resistance.
