The Design of the Weak Signal Conditioning Circuit
This paper describes the design of weak signal conditioning circuit. The amplitude of weak signal is very small and can easily be submerged by the noise, so when we choose the component for the circuit, in order to diminish the noise of the conditioning circuit, we choose a kind of low-noise operational amplifier for conditioning the signal. This circuit is applicable to the slow-varying direct current signal, even when the amplitude of the signal is dozens of microvolt, it still can work as normal.
