Abstract
A duty cycle-based bit interface system includes a first stage voltage converter and second stage voltage converter in signal communication with the first stage voltage converter. The first stage voltage converter converts a digital voltage signal into an analog voltage signal. The second stage voltage converters convert the digital voltage signal into a scaled version of the same. A sampling unit is in signal communication with at least one of the second stage voltage converters, and is configured to sample a portion of the first stage analog output voltage signal during a sampling time period. The sampled portion has a duty cycle based-analog voltage signal during the sampling time period. A bit selector unit is in signal communication with the sampling unit, and outputs a bit enable signal that initiates a specific diagnostic test among a plurality of diagnostic tests based on the duty cycle of the sampled portion.
