GaAs Integrated Circuit Technology for High Speed Analog and Digital Electronics

Ultra-high speed GaAs digital and analog integrated circuits are being developed to meet high throughput requirements for very fast signal processing in telecommunications or military systems as well as for commercial very high speed computers. To achieve high system performance, the “on-chip” delay must be minimized. Also a LSI (VLSI) level must be reached (2.000 to 10.000 gates/chip) for digital IC’s. The GaAs technology is then confronted to LSI problems such as parameters uniformity and yield. On the other hand, analog circuitry needs precision operators and high stability.
