Originální abstrakt

This paper presents the design and noise measurements of amplifier suitable for use with modern integrated A/D converters. Proposed topology is capable of both amplifying and attenuating its input signal to utilize the whole input voltage range of A/D converters. Experimental version achieved full-scale input voltage range from ±15 V to ±15 mV with measured input voltage noise of 0,17 ppm to 0,73 ppm of full-scale range. Suppression of offset error associated with amplifier and A/D converter systems is realized using auto-zero scheme. Resulting amplifier used in conjunction with digital filters can achieve more than 20 noise free bits on all gain settings.
