Items 1 - 25 of Collapse Attributes.  · To advance the technology for practical applications, we developed a ring modulator with reverse-biased pn-junction modulation to achieve both low capacitance and low drive voltage. We designed a low-power CMOS driver and integrated the modulator with driver circuits into a complete, functional electro-optic device.

Gb/s Limiting Amplifier and Laser/Modulator Driver in m CMOS Technology Sherif Galal, Student Member, IEEE, and Behzad Razavi, Fellow, IEEE Abstract— A limiting amplifier incorporates active feedback, inductive peaking, and negative Miller capacitance to achieve a voltage gain of 50 dB, a bandwidth of GHz, and a sensitivity. Loss compensation gain cells using series-shunt peaking technique and stacked-FETs were incorporated into a modulator driver based on distributed topology to improve the bandwidth. The driver was developed in nm CMOS technology. It can integrate with digital circuits on a chip. Hence the cost of optical transmitters will be considerably reduced. The driver was evaluated with. We report the first sub-picojoule per bit (fJ/bit) operation of a silicon modulator intimately integrated with a driver circuit and embedded in a clocked digital transmitter. We show a wall-plug power efficiency below µW/Gbps for a nm SOI CMOS carrier-depletion ring modulator flip-chip integrated to a 90nm bulk Si CMOS driver circuit. We also demonstrate stable error-free.
