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 ∑Δ 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 ∑Δ 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.
