ABSTRACT
Analogue-to-digital converters (ADCs) find widespread use in consumer as well as professional electronics. Examples are digital tape recorders, digitizing oscilloscopes, transient recorders etc. To date only semiconductor ADCs are being used, but it is expected that due to the ever-growing demand for increase in speed and accuracy opportunities for their superconductor counterparts will present themselves. An example is the need in some radar systems to view both large and small signals simultaneously (Przybysz 1993). This requires the use of 16-bit converters having an input signal bandwidth of 10 MHz. Achieving this in semiconductor technology has so far remained elusive although steady progress is being made.
