MANY MONOLITHIC D/A and A/D converters have beendeveloped' ' 2 , prompted by the increasing use of digital signal processing. This paper will describe an integrated circuit 13b A/D converter which is suitable for pulse code modulation. It is of the successive-approximation type, with a 1 6 ,~s conversion time and l / 2 LSB accuracy. The converter includes a sample/ hold circuit on a chip aiming at the realization of a monolithic
IC.A functional block diagram is shown in Figure 1. The circuit incorporates cotn…
