Abstract
System and method for digitizing analog voltage signals. A first voltage signal may be received at a comparator. A ramp signal may be received at the comparator. The ramp signal may be generated by a ramp generator. An output signal may be generated by the comparator. The output signal may indicate whether the analog voltage signal or the ramp signal is greater. The output signal may be conveyed to logic circuitry by the comparator. Control information may be conveyed by the logic circuitry to the ramp generator. The ramp generator may generate the ramp signal based on the control information. The logic circuitry may determine a digital representation of the first voltage signal based on the output signal from the comparator and the control information.
