Abstract

High-resolution bio-imaging is a key component for the advancement of life science. CMOS electronics is one of the promising candidates for emerging high-resolution devices because it offers nano-scale transistors. However, the resolution of the existing CMOS bio-imaging devices is several micrometers, which is insufficient for analyzing small objects such as bacteria and viruses. This paper presents the results of an analysis of the scalability of a current-mode analog-to-time converter (CMATC) to develop a high-resolution CMOS biosensor array. Simulations were performed using 0.6-µm, 0.25-µm, and 0.065-µm CMOS technology nodes. The Simulation results for the power consumption and resolution (cell size) showed that the CMATC has high-scalability and is a promising candidate to enable high-resolution CMOS bio-imaging.
