Abstract:
A monolithic +or-5-1/2-digit BiMOS analog-digital converter that achieves integral integrity within two counts over the range -2 V to +2 V and noise error for any single reading within +or-1 count is described. The part uses four noncritical external passive components; the reference voltage is also provided externally. The converter uses a three-pass algorithm with a modified dual-slope integration and subsequent residue multiplication steps. It has been integrated on a BiMOS process based on a production 4- mu m CMOS process with one mask added and the starting material polarity changed.<>
