Abstract
Abstract—This paper presents a 12-channel parallel 40Gb/s laser diode driver (LDD) realized in 0.35μm SiGe BiCMOS technology. The single channel works at bite rate of 3.318Gb/s. A “cross couple” capacitance cancel technique is used to increase bandwidth. To avoid substrate coupling noise brought by the adjacent channel, an isolation method for parallel amplifier is used. The measured results show the LDD can supply 5-20mA modulation current and 2-5mA bias current.
