Design and Simulation of Photoelectric Detection Circuit for Microfluidics Chip

Abstract:

This paper presents a photoelectric detection circuit for microfluidics chip. The proposed photoelectric detection system can reduce noise and increase sensitivity. It is consist of pre-amplifier, ac-amplifier and band-pass filter. The transfer function of photoelectric detection circuit is introduced. The circuit implementations and simulation results are given. The proposed photoelectric detection circuit is suitable for integrated microfluidics chip.
