Abstract

Systems, devices, and methods for continuous-time digital signal processing and signal representation are disclosed. This includes a continuous-time analog-to-digital converter that is configured to receive an analog signal and convert it to a continuous-time digital signal without using a clock or any type of sampling. This A/D conversion can include a per-level representation and a per-edge representation of the analog signal to produce a digital signal. The digital signal can then be processed in a continuous-time signal processor. The continuous time signal representation and processing can have benefits such a providing filters in high frequency applications where sampling is not practical.
