Abstract
A new scheme has been developed for a 4096-channel (12-bit) successive approximation ADC which will allow more rapid coding than schemes commonly used at the present time. The allowable bit setting time for the major bits has been increased without adding to the total coding time. This is accomplished by permitting the initial accuracy of the setting of the major bits to be within eight channels. Towards the end of the coding time, when the major bits have settled, this error is corrected to an accuracy of a fraction of a channel. Using this scheme a differential nonlinearity of better than 20% has been achieved in the basic encoder with a total coding time of 4 ..mu..s. Applying a 6-bit sliding register (the method of Gatti) to the ADC, a differential nonlinearity less than 0.5% results in the complete ADC.
