Abstract:
A kind of sampling circuits of piezoelectric biosensor is designed based on the CPLD devices. It is realized that 10 MHz high frequency signal measure and sampling, data display and data serial communication etc. The system has been proved to have high reliability, good real-time performance. The system architecture are discussed in detail including hardware and software, and the implementation. The simulation result of CPLD kernel and the frequency curve by sample soft are shown.
