Cross-type daisy chain enables charge recycling and achieves power reduction while keeping communication performance such as high timing margin, low bit error rate and high bandwidth. There are two design issues in cross-type daisy, one is pulse amplitude reduction and another is inter-channel skew. To compensate them, inductor design and replica circuit is proposed and investigated. Test chips were designed and fabricated in 90 nm CMOS to verify the proposed transmitter.

The smaller transceiver design in turn lowers the clock distribution power and improves the signal quality by presenting less loading to the clock and the channel, respectively. The improved signal quality enables even lower signal swing and a ldquospiral of goodnessrdquo continues.
