FPGA based design of a control system for electrophoresis on PCR microfluidic chip

A control system for PCR microfluidic chip is designed and realized in this paper. The serial Controlled A/D and D/A chips are chosen to reduce the amount of control ports. FPGA with plenty of control ports is chosen to be system MCU, on which programming in VerilogHDL, and as a result 30 PCR chips can be controlled synchronously. Communication between PC and USB2.0 high-speed transfer interface chip are applied to meet the needs of control and uploading data. we compiled Windows xp based driver and control software, in addition. Conclusively, the system parallel control multiple chips to improve the detecting efficiency and can be used when detecting for large quantity of chips is needed.
