Abstract

A daisy chain of current-driven transmitters in inductive-coupling complementary metal oxide semiconductor (CMOS) links is presented. Transmitter power can be reduced since current is reused by multiple transmitters. Eight transceivers are arranged with a pitch of 20 μm in 0.18 μm CMOS. Transmitter power is reduced by 35 without sacrificing either the data rate (1 Gb/s/ch) or BER (< 10-12) by using a 4-transmitter daisy chain. A coding technique for efficient use of daisy chain transmitters is also proposed. With the proposed coding technique, additional power reduction can be achieved.
