A FIRST ORDER INCREMENTAL ANALOG TO DIGITAL CONVERTER BASED ON CONTINUOUS TIME CIRCUITS
Ricardo Doldan, Alberto Yufera, Adoracion Rueda
Abstract:
In this paper, an incremental Analog-to-Digital Converter (ADC) designed as part of the signal-conditioning circuitry for tissue impedance measurement system is presented. Continuous-time design techniques has been used and a modified implementation of the conversion algorithm, with respect to its discrete-time counterpart, has been developed. To reduce the influence of the no-idealities, analog and digital corrections have been also implemented. A prototype in 0.8 µm CMOS technology has been fabricated and tested. Experimental results are reported.
