Abstract

This study proposes a circuit architecture suitable for designing a wide dynamic range current-to-time converter, and suitable for potentiostat design meeting different requirements. Therefore, this study provides an efficient way to make trade-offs among the parameters, such as dynamic range, sampling frequency, resolution, power dissipation, and chip area. A time-based potentiostat for wide dynamic range current measurement is presented. The proposed design is characterized through post-layout simulation, showing a wide dynamic input current range of 126 dB (1 nA-2 mA), and the resolution at the minimum current range is smaller than 10 pA. The sampling frequency of the circuit is 1 kHz, and the minimum power dissipation is only 12 μW.
