Original Abstract

The switched offset compensation of an operational amplifier was designed in AMIS CMOS07 technology as one of the main parts of the electrochemical sensor measurement system. Usual offset of operational amplifiers in the technology is about 10mV-15mV, but measured signal value was in between 10mV-100mV with desired maximum error lower than 5%. By this solution we are able to compensate the mentioned opamp offset as well as the voltage drop at the switch connected in serie with measured sensor.
