Speed, power consumption, and impedance in gallium arsenide IC interconnection circuits

摘要

The goal of this project is to determine the feasibility of conserving power while maintaining reasonably high speed in Gallium Arsenide integrated circuit interconnection circuits by increasing the characteristic impedance of microstrip or stripline printed circuit board. This thesis presents the modeling and simulation of output driver and input receiver circuits for Gallium Arsenide digital ICs. Impedance controlled printed circuit board transmission lines are also studied. MATLAB is used to model and calculate the impedance that can be obtained using a microstrip and/or stripline printed circuit board interconnect. This information is then used with HSPICE to model and simulate transmission line interconnects. HSPICE is also used to model and simulate the design of the output driver and input receiver circuits for use with the printed circuit board. Finally, the IC is layed out using MAGIC to show differences in circuit size at different impedances.
