Abstract. Optical-electronic system with operational amplifiers used for comparison of slowly varying sensor signals is considered. Methods of zero drift correction employed in such systems are analyzed. A new method is proposed which ensures compensation of output signal bias voltage.
Keywords:
operational amplifier, zero drift, zero correction, optical-electronic system.
