Abstract:A charge-recycled amplifier-less current-to-digital converter (CDC) is presented in this paper. The highly digital CDC is based on ultra-low-power subthreshold operation, amplifier-free design, scalable current range, and high-resolution digital circuits. It is realized using a mixed-signal approach by utilizing an analog comparator, 6-bits current steering DAC, an implicit passive integrator, and digital signal conditioning circuits. The proposed converter can be operated in tri-modes to support multiple curr… Show more
