In this episode of Chalk Talk (sponsored by Infineon Technologies and Mouser Electronics), Amelia Dalton and Daniel Callen Jr. from Infineon explore trends in solid state isolator and relay solutions, the benefits that Infineon’s SSI solutions bring to the table, and how you can get started using these solutions for your next design. https://lnkd.in/edMbSfN7

This week, the market price of wafers was "reverse differentiated" again, with P-type wafers holding steady and N-type wafers falling again, and the price spread between N and P further inverted. The price of N-type wafers has accumulated a large amount of inventory during the Spring Festival and further accumulated inventory after the holiday, due to the increase in wafer production scheduling after the holiday, and the price of N-type wafers has fallen due to fierce market competition. PERC 210 cell prices remained stable, the quotation of Topcon 210 cells was raised by 1-2 cents/W. This week, N-type cell profits recovered due to the reduction in the actual transaction price of N-type wafers, but the actual transaction price of cells is difficult to increase in the short term, mainly due to the weak acceptance of the module side. #modules #perc #wafers #solarcell

Advanced in-situ #etch depth control for dry etching processes – to achieve optimum device performance. We explain exemplarily how to control the etch depth in-situ & why the measuring wavelengths of the interferometer must be adapted to the material properties. 👉https://fbhlink.de/j80w These activities were partly funded by BMBF within the framework of FMD - Forschungsfabrik Mikroelektronik Deutschland.

mytreya kasturi asked me this interesting question: is it better to use an active-low or an active-high reset signal on digital blocks? Most designs use an active-low reset signal, meaning the system is in reset when the signal is low. It seems to me that this is the logical way to do it. The reset signal is then released when Vcc is high enough after power on. In ye olde days, we used to tie RESETn to Vcc with a pull-up resistor. Maybe even using a capacitor to delay it a bit. The better approach is to use a dedicated reset IC which only releases reset when Vcc is stable. Most systems require multiple voltages and these must be started in a particular order. Therefore, many MCUs come with a "Companion Chip" that provides power sequencing and an external watchdog. Such a chip also provides a reset signal.
