Zero Drift Automatic Suppression Technology for Non-Inertia Integrating Circuit Based on C8051F350 MCU

Abstract:

The non-inertia integration circuit is a basic segment for the reduction of DC or low-frequency small signals. Whether the circuit can work normally or not depends on zero drift. Through a detailed study of a certain non-inertia integrating circuit, this paper has proposed a kind of zero drift technology based on C8051F350 to automatically suppress the drift voltage from the input of the operational amplifier by injecting the suppression signals into the input of the amplifier directly. This technology is designed to ensure that the integrating circuit can work accurately for more than 10 seconds. The experiments have shown that the technology is effective and feasible.
