ABSTRACT:
Using an operational amplifier with a low gain in a closed loop amplifier circuit, and correcting for errors (i.e., deviation from the output of an ideal closed loop amplifier using an operational amplifier with infinite gain) that would result from the use of the operational amplifier with low gain. In an embodiment implemented in relation to an analog to digital converter (ADC), a mathematical operation is performed on the digital code(s) generated by the ADC to generate a corrected code corresponding to an analog sample.
