TODAY'S HIGH-SPEED LOGIC DEMANDS MAJOR ADVANCES IN CIRCUIT DESIGN AND PACKAGING
Advanced high-performance systems require fast logic and memory circuits in order to meet data and signal processing requirements. VHSIC (very high speed integrated circuits) and other high-speed logic (GaAs, ECL, FAST, FACT, and AS)(*) require major advances in circuit design and packaging philosophy to achieve high performance in a reliable fashion.
In the past, digital systems for most applications used clock frequencies in the order of 5 to 10 MHz and were usually implemented with TTL, NMOS or CMOS logic. These logic circuits had negligible high-frequency content in their
