Abstract

This paper proposes a design technique to reduce the power dissipation of CML driver for on-chip transmission-lines. CML drivers can operate at higher frequency than conventional static CMOS logic drivers. On the other hand, the power dissipation is larger than that of CMOS static logic drivers. The proposed method reduces the power dissipation by using an impedance-unmatched driver instead of the conventional impedance-matched driver. Measurement results show that the proposed method reduces the power dissipation by 32% compared with a conventional design at 12.5Gbps.
