  1. ; (, 2022 IEEE 15th Dallas Circuit And System Conference (DCAS))
    Presented in this paper is the design of a level-crossing ADC for biomedical potentials. This architecture takes advantage of the time sparse nature of neural signal recording applications by only sampling when the signal is moving. A 10-bit architecture with a novel threshold control scheme was chosen to help capture both the higher amplitude local field potentials and lower amplitude action potentials found in these systems. The ADC operates on a power of 13.5μW from a 1.8 V supply and achieves a root-mean-square error (RMSE) of 0.65 mV. The design is implemented and simulated in a 180 nm CMOS process using the Cadence Virtuoso Custom IC design tool.
