Latest Patents

**Bandgap Reference Voltage Generation Device.** This invention combines a proportional-to-absolute-temperature (PTAT) current generator, a bandgap reference voltage generation circuit, and a current compensator. The compensator retrieves two PTAT currents with different positive temperature coefficients, performs subtraction and addition to produce a compensation current, and sends it to the generation circuit to produce a voltage with a zero temperature coefficient.

**Ramp Generator and Image Sensing Device.** This ramp generator uses a digital-to-analog converter to produce ramp-up and ramp-down voltage signals. Two capacitors connect the converter’s output terminals to an intermediate node, where a noise cancellation circuit provides compensation feedback based on the intermediate voltage.
