| 20100156501 | Adjustable integrator using a single capacitance - An integrating amplifier on an IC, which comprises a feedback loop using an external device as an integrating capacitor, has added a second feedback loop that provides an additional current to the input of the amplifier, which current can be used to increase the input range of the charge that can be measured without needing another external capacitor or pad. | 06-24-2010 |
| 20100289590 | Self-trim and self-test of on-chip values - A self-trim circuit provides a technique to trim a CUT (circuit under trim) using a LSB offset to determine the best digital value to trim the CUT. The self-trim circuit is also used to self-test the digital and analog portions of the self-trim circuitry, whereby the existence of a digital stuck at fault condition is detected. A state machine controls a digital stack to couple digital trim data to the CUT and read the output of a comparator circuit that signifies when a proper digital trim value has been used. Thereafter the proper digital trim value is stored into a nonvolatile memory. | 11-18-2010 |
