Differential-type Structures and C-elements for GaAs MESFET Asynchronous Circuits
نویسندگان
چکیده
In any high-speed digital circuit, problems like clock skew, transmission delays and off-chip communication are worrisome. Being particularly fast, GaAs technology is a good candidate for global clock free design. In this paper, a detailed analysis of several differential-type structures and C-elements, used to build self-timed delay-insensitive circuits, is carried out by HSPICE simulations in terms of speed and power dissipation. These structures were used to evaluate three versions of a GaAs self-timed ring divider. The comparison reinforces the previous analysis.
