GaAs Based Digital Serial Communications System

摘要

This thesis concerns the design and simulation of a one gigabit per second synchronous transmitter and receiver system. The circuitry is to be integrated on a 32-pin gallium arsenide semicustom digital gate array. Digital logic components are built using enhancement and depletion mode n-channel metal-semiconductor field-effect transistors. The computer simulations indicate that, under a one micron gate process technology and using a 2V voltage supply, inverter propagation delays as small as 60 picoseconds can be achieved. Designs for both the transmitter and the receiver have been successfully simulated at the one gigahertz clock rate. Keywords include: GaAs integrated circuits; GaAs MESFET computer model; Semi-custom gate array; High-speed digital communications; and Fiber optic transmission system.
