Claim 7:
8. The digital sensor of claim 5, the slew-rate controlled output buffer further comprising a pre-driver coupled to the output driver and configured to:
enable the first current sink circuit and connect it to the first feedback capacitor when the first transistor needs to be enabled;
disable the first current sink circuit and connect the second current sink circuit to the first feedback capacitor, and pullup a gate of the first driver when the first transistor needs to be disabled;
enable the first current source circuit and connect it to the second feedback capacitor when the second transistor needs to be enabled; and
disable the first current source circuit connect second current source circuit to the second feedback capacitor and pulldown a gate of the second driver when the second transistor needs to be disabled.
