Abstract

The use of microprocessors in data conversion is receiving increasing interest. This does not only boost circuits reliability, reduce number of components but it also adds new dimensions in converter design. Software simulation of some co-mplex functions such as successive approximation registers, priority encoders... etc. could be in several cases of advatage. 
In this paper two microprocessor-based A/D converter circuits are suggested and tested. With a premitive microcomputer system ( University Board TMS 9980) sampling rates of 3257 sample/sec for a 12-bit successive approximation routine and 9416 sample/sec for a 6-bit cyclic-flash structure were obtained. Other measured results are promising and depend mainly on the used comparators. 
The tested techniques are suitable for a multitude of applications such as comp liter tomography, digital recording of sound signals ... etc.
