Abstract

This paper describes the design of an active CMOS biosensor array for fluorescence-based assays which enables time-gated, time-resolved fluorescence spectroscopy. The array is sensitive to photon densities as low as 1.15 × 108/cm2, has a dynamic range of over 74 dB, and has sub-nanosecond timing resolution. High sensitivity is achieved through subsampling and averaging.
