This paper presents a 10-μA, trim-free, low temperature coefficient, supply independent current reference with process compensation feature. Based on the proposed structure, a 130 ppm/°C temperature coefficient current reference across -40°C to 80°C temperature range is achieved. The proposed circuit can work at supply voltage(More)
This paper presents an Integrated Power Module (IPM) and an Integrated Power Unit (IPU) which are based on the IGBT double sided cooling technology. The IPU can be used as the motor control inverter in the electric vehicle. While the IPM used in the IPU is packaged with latest 650V trench field-stop IGBT device and double sided cooling technology. With the(More)
An ordered, homogeneously distributed and uniform 0.9 nm Ag array, which exhibits an unusual UV-vis surface plasmon resonance absorption peak at 355 nm with the largest blue-shift position and controllable intensity, has been successfully prepared by a simple soft chemical approach using the nanoporous VSB-1 as the template.
