Abstract :
This paper presents a design of power efficient and high speed transmitter implemented in CMOS 180 nm UMC technology, fully compatible with low voltage differential signaling (LVDS) standard specified by IEEE. The main stand-alone driver´s functional blocks: LVDS core, common mode feedback (CMFB), control buffer and band-gap reference source are described in detail. Three architectures of LVDS transmitter cores: bridged-switched current source (BSCS), double current source (DCS) and open drain (OD) are compared and finally the BSCS architecture is selected due to project´s requirements. The designed LVDS driver characterizes a very low level of static and dynamic power dissipation, Pstat = 7.5 mW and Pdyn = 11.6 mW respectively, at data speed transmission 1.8Gb/s with receiver´s input capacitance CR = 1 pF and Pdyn = 8.5 mW, data rates equals 400 Mb/s at CR = 5 pF.
