Methods of calibrating linearizing circuits.

摘要

A linearizing circuit (10) for devices having logarithmic outputs, such as an electrolytic oxygen detector (12), comprises an inverting biasing circuit (14) and a scaling circuit (16) connected to an antilog function generator (18). The circuit (10) is calibrated by zeroing the inverting biasing circuit (14) at an extreme point of the desired range and scaling a second point on the desired range in the scaling circuit (16).
