Analog- Digital LSI on the E⁺ᵗ Curve

Abstract

The title of this paper was selected to indicate that large scale integration (LSI) of analog (linear), digital and combined monolithic analog and digital (A & D) circuits for telecommunication systems is progressing at an exponential rate. As is the case with exponential functions, near term (i.e., when t is small) increases are rather modest, but, once started, the function grows rapidly. This is the case of A & D LSI: it is just starting to take hold, and impressive gains are expected in the future. The purpose of this paper is to explore, from the system point of view, some of the recent technology developments that have taken place and that are expected to impact the design of future telemetry, communication and sensor equipment.
