Abstract
An electronic device includes an analog front end (AFE) circuit including plural modules, and a processor that provides a user interface for a firmware update, determines a target module, of which offset calibration is to be performed, among the plural modules, based on a user input to the user interface, determines a position within in the AFE circuit to which a common mode voltage is to be applied to perform the offset calibration of the target module, and determines an offset calibration sequence including the target module and the position.

- determine an offset calibration sequence including the target module and the position.
A method comprising:
- providing a user interface for firmware update;
- based on a user input to the user interface, determining a target module, for which offset calibration is to be performed, among a plurality of modules included in an analog front end (AFE) circuit;
- determining a position within the AFE circuit to which a common mode voltage is to be applied for performing the offset calibration of the target module;
- and
- determining a calibration sequence including the target module and the position.
An analog front end (AFE) circuit comprising:
