Abstract

The present disclosure relates to a signal conditioning system for improving low-frequency measurement performance of an acceleration sensor. The signal conditioning system includes: a charge integration circuit, a high-pass filter circuit, a lead-lag network, an anti-aliasing filter circuit, and a gain adjustment circuit. An input terminal of the charge integration circuit is connected to the acceleration sensor, an output terminal of the charge integration circuit is connected to an input terminal of the high-pass filter circuit, an output terminal of the high-pass filter circuit is connected to an input terminal of the lead-lag network, an output terminal of the lead-lag network is connected to an input terminal of the anti-aliasing filter circuit, and an output terminal of the anti-aliasing filter circuit is connected to an input terminal of the gain adjustment circuit.
