Stack Exchange network consists of 182 Q&A communities including Stack Overflow, the largest, most trusted online community for . Why are there so few electronics-centric people online? I would like to measure the distance within accuracy of 1 mm. I agree that Electronics is really a better name than Chiphacker because my favorite questions at Chiphacker were not about circuits using integrated circuits (chips) but about those with discrete components. SCK - clock MOSI - master out slave in (typically data from microcontroller to IC) MISO - master in slave (typically data from IC back to microcontroller) SS - slave select. 1,763; asked Feb 12 at 13:28. With CMOS you end up with smaller circuits which is great because we can fit more logic gates into our designs which may be quite small. It's clearly the most suitable component to use here, but it comes with a bunch of nuisances in the discrete application that go away in most integrated circuits where the substrate is not tied to the FET source but is a separate die layer that will get tied to one of the supply voltages. Discrete small MOSFETs would be very delicate and sensitive to ESD; therefore they are not comonly available or used.

Share knowledge. In general, I would say that the types of MOSFET that you can buy as discrete components are better at switching than BJTs, and the types of BJT you can buy discrete are better at linear operation. Else find the max value and assign it to answer 5. return answer MOSFETs have wide parameter variation which makes them more amicable to digital than analog applications and/or requires larger support circuitry around them which makes them more suitable for integrated circuits.

Monica wants to buy a keyboard and a USB drive from her favorite electronics store. Even disregarding voltage, IGBTs are at advantage when the loss caused by the transistor's implicit diode is lower than that caused by the FET's channel resistance. Another reason why ASIC and FPGA belong on the same stack exchange board, is because anybody that designs an FPGA can go to xilinx or intel and pay them a fee to convert their FPGA design into an ASIC design. Low voltage switched mode power supplies usually use MOSFETs. For example MOSFETs have lower source-drain voltage drop than BJTs have collector-emitter voltage drop if you have reasonable (not too high) currents.
