Abstract
In this paper, a 4-channel common-cathode VCSEL diode driver array with 3.125 Gb/s per channel operation speed is realized. In order to achieve faster speed of the switching main driver with relatively large transistors, the transmitter array chip consists of a pre-amplifier with active inductor stage and also an input buffer with modified equalizer, which leads to bandwidth extension and reduced current consumption. The utilized VCSEL diode provides inherently 2.2 V forward bias voltage, $50{\Omega}$ resistance, and 850 fF capacitance. In addition, the main driver based upon current steering technique is designed, so that two individual current sources can provide bias currents of 3.0 mA and modulation currents of 3.3 mA to VCSEL diodes. The proposed 4-channel VCSEL driver array has been implemented by using a $0.11-{\mu}m$ CMOS technology, and the chip core occupies the area of $0.15{\times}0.18{\mu}m^2$ and dissipates 22.3 mW per channel.
