Abstract

This paper introduces a kind of receiver that can receive signal which weak to UV level. First, the common mode rejection for the input differential signal is necessary, and a low noise amplifier followed by. Then we should let the signal go through a Programmable filter whose center frequency, Q are all selected via pin-strapped inputs. In order to get the appropriate amplitude of the signal, an automatic gain control amplifier is needed. Last, before the signal sampled by the A/D converters, an active filter and an operational amplifier is followed by the AGC amplifier. Through the actual test, the low frequency signal receiver with high sensitivity introduced in this paper has the characteristics of high sensitivity and stability, so it can be applied in some engineering.
