| Abstract: | There are several problems in the previous studies of the calibration process for signal conditioning circuits of piezoelectric acceleration sensor,such as tedious procedure and low efficiency.Besides,the output signal gain of signal conditioning circuit cannot be adjusted during the running process.To solve those problems,this paper describes a new method that a variable gain operational amplifier controlled by a micro controller is employed behind the prime charge amplifier to achieve real-time control of... |
