    摘要： According to one embodiment, there is provided a high voltage drive circuit comprising drive and sense electrodes formed substantially in a single plane. The device effects signal transfer between drive and receive circuits through the drive and sense electrodes by capacitive means, and permits high voltage devices, such as IGBTs, to be driven thereby without the use of high voltage transistors, thereby eliminating the need to use expensive fabrication processes such as SOI when manufacturing high voltage gate drive circuits and ICs. The device may be formed in a small package using, by way of example, using CMOS or other conventional low-cost semiconductor fabrication and packaging processes.

    摘要： A light sensor having a photocurrent subsection and an interface circuit is disclosed. The photocurrent subsection includes a photodetector, an amplifier, a diode and an impedance element. The first photodetector generates a current between a first node and a power rail in response to being illuminated with light. The interface circuit generates an output signal that is related to the logarithm of the intensity of light that is incident on the photodetector. The impedance element is constructed in a manner that compensates for the thermal dependency of the impedance through the diode. Additional photocurrent subsections can be added to further reduce the thermal dependency of the output signal.
