Versatile SAR-ADC for Biomedical Applications
Résumé
This paper presents a versatile SAR ADC targeting
the acquisition of signals in biomedical applications. The converter
is implemented in a CMOS AMS 0.35m technology and
powered with 3.3V. Its output bit-width can be varied from 4 to 8
bits. The device includes built-in programmable clock generator
and voltage reference circuit. The sampling rate can be tuned up
to 100kS/s in the 8-bit mode and with a maximal input range of
2.5V. All these parameters can be independently adjusted. This is
an unique fully-configurable converter. The simulation results are
reported and positioned with respect to the most recent designs
