| Popis: | Comunicación presentada al "XVII IMEKO World Congress: Metrology in the 3rd Millennium" celebrado en Dubrovnik (croacia) del 22 al 28 de Junio del 2003. In this paper, an incremental Analog-to- Digital Converter (ADC) designed as part of the signalconditioning 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 0.8μm CMOS technology has been fabricated and tested. Experimental results are reported. |
