Abstract
This invention includes a current output sensor, and a current AD conversion means which is connected to the output side of the current output sensor and has a current mirror circuit arranged on the input side of a comparator in order to directly A/D-convert an output from the current output sensor. A signal can be stably processed with a small circuit scale and low current consumption.
Claims9
A semiconductor integrated circuit comprising:
- a current output sensor;
- and
- current AD conversion means connected to an output side of said current output sensor to connect an output from said current output sensor to an input side of a comparator via a current mirror circuit and A/D-convert the output from said current output sensor.
Dependencies are inferred from the claim text.
