A novel low‐power, tuneable resolution and low‐current sensing analog‐to‐digital converter is proposed in this paper. The proposed architecture consists of silicon neurons along with digital circuits. The architecture is tuned for input signal ranging from 100 nA to 3.3 μA with power supply of 1 V/3.3 V for digital blocks and silicon neurons respectively. The design is simulated using 0.18 μm CMOS 1P4M triple well process of Tower Jazz Semiconductor's technology. Total power consumption of the circuit is 98.8 μW and achieves FoM of 14.74 pJ/Conv for 8‐bits of operation. © 2021 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.
