In this paper, a 12.5-Gb/s optical transmitter is implemented using 0.13-μm CMOS technology. The optical transmitter that we constructed compensates temperature effects of VCSEL (Vertical cavity surface emitting laser) using auto-power control (APC) and auto-modulation control (AMC). An external monitoring photodiode (MPD) detects optical power and modulation. The proposed APC and AMC demonstrate 5~20-mA of bias-current control and 5~20-mA of modulation-current control, respectively. To enhance the bandwidth of the optical transmitter, an active feedback amplifier with negative capacitance compensation is exploited. The whole chip consumes only 140.4-mW of DC power at a single 1.8-V supply under the maximum modulation and bias currents, and occupies the area of 1280-μm by 330-μm excluding bonding pads.

“…But the bottlenecks, such as clock signal skew, limited bandwidth, input signal delay and so on, limits the transmission speed inter-chips. Data rates will be enormously increased with the development of optical interconnection in the future, which can overcome the shortcomings of the conventional metallic transmission media [1]. Laser driver is the principle part in optical interconnection.…”

A 12-channel 120Gb/s laser diode driver array has been designed in 0.18μm CMOS technology. Under a supply voltage of 1.8V, simulated results show that a single channel has a speed of 10Gb/s at a power consumption of 98mW. A total capacity of 120 Gb/s can be obtained from 12 channels. With three stages of differential amplifiers directly coupled, the single channel amplifier can supply the current up to 26mA adopting negative feedback and capacitive coupled current amplifier (C 3 A) structure. The adjustable modulation current from 1mA to 16mA and the bias current up to 10mA can be generated from this driver circuit. The layout area of the driver array is 3205μm×506μm. This design can be used in high speed optical chips. Keywords-laser diode driver array; 12 channels; C 3 A; active negative feedbackI.

“…Optical interconnects, with potential speed into Terabits/s, are expected to be one of the best solutions to overcome the bottleneck in bandwidth, transmission distance, and electromagnetic interference in conventional metallic transmission media. Moreover, characteristics such as low crosstalk, low loss, and low distortion make parallel optical interconnects well suited to VSR (very short reach) applications such as chip-to-chip or board-to-board interconnection [1]. In such optical interconnects, an important component is the high performance driver.…”

A design of 10Gb/s VCSEL driver IC in 0.18μm CMOS process is presented. Employing directly coupled three stages of differential amplifiers, active degenerative feedback and C3A structure, the monolithically integrated circuit can amplify the amplitude of input differential signal to 22mA and offer a bandwidth of 9.4GHz at 10Gb/s with a total power consumption of about 91mW. The driver circuit can offer adjustable modulation current from 1 to 16mA and adjustable bias current from 1 to 10mA. The VCSEL driver can be used in the STM-64 optical fiber communication system.
