... Calibration Function In order to achieve superior linearity, the CXD2310AR has a built-in calibration circuit. In order to eliminate the necessity for the externally input calibration pulse required by the earlier CXD2310R, a startup calibration function and an auto calibration pulse generation function have been newly added to the CXD2310AR. Fig. 1 shows a block diagram of the calibration pulse generation circuit ...
