摘要：

The proposed sensor interface minimizes the optical detection system size while maximizing its overall efficiency (both power and sensitivity) of a multi-stage microfluidic cell sorter system. The proposed Sigma Delta sensor interface achieves at least one order of magnitude higher sensitivity while consuming less power (2mW) as compared to the traditional operational amplifier based transimpedance amplifier sensor interface. The proposed Sigma Delta sensor interface will be used to complete a full implementation of the developed multi-stage microfluidic system that would prove to be a great advancement in microfluidic cell sorting technology.
