Abstract :
This paper describes the design and performance of a mixed signal, very high-speed data conversion chip for wireless communication systems implemented using gallium arsenide (GaAs) MESFET technology. The mixed analog-digital circuit uses source coupled MESFET logic for analog components and GaAs merged logic for digital components. The design is module oriented, thus enabling easy cascading into a multi-bit data conversion chip. The chip was implemented with 400 devices and dissipated 185.6 milliwatts of power. The conversion time was 0.75 nsec with a noise margin of 0.35 volts. These results indicate the validation of the design technology and techniques used for mixed analog-digital circuit design on a single chip
