—This paper presents the design of three-and nine-stage voltage-controlled ring oscillators that were fabricated in TSMC 0.18-m CMOS technology with oscillation frequencies up to 5.9 GHz. The circuits use a multiple-pass loop architecture and delay stages with cross-coupled FETs to aid in the switching speed and to improve the noise parameters. Measurements(More)
The discussions we made had a profound effect on the direction of my research. During the course of my stay at Georgia Institute of Technology, I had the chance to interact with many distinguished faculty members. I would like to thank Prof. Sean Lee for the insights he gave about the semiconductor industry. I would like to thank Prof. Wills for the(More)
—A senior-level design laboratory course is described, in which an optical fiber communication network is expanded or improved by successive generations of students. In this evolutionary approach, student teams base their work on the final written reports of students in previous course offerings. In addition to its primary goal of providing a high-level(More)
