Sep 25, 2013 · SiGe is a semiconductor alloy, meaning a mixture of two elements, silicon and germanium. Since 2000 or so, SiGe has become widely used to enhance the performance of ICs of …

Aug 26, 2018 · Are SiGe NPN transistors used to build digital gates? Yes. This is done either for very simple, small logic, when you might need a few hundred control gates in a power amplifier or similar …

Nov 30, 2015 · Could you suggest if it's possible to effectively use SiGe/GaAs RF MMIC (which have 50 Ohm input impedance) as first stage of photodiode amplifier? The idea is to reverse bias diode from …

Jan 22, 2024 · You can make SiGe bipolar transistors (on a chip) with ft's approaching 100GHz, and 4000 series CMOS (enhancement mode MOSFETS) that struggle to switch at 5MHz with low supply …

Dec 29, 2025 · I am at the final stage of making my inductive vehicle sensor based on an oscillator. I'm planning to reach around ~100-ish kHz I only need to make the inductor for this project and I've …

Oct 9, 2020 · Your assignment statement: temp2<=(resize(to_sfixed(temp2_32,3,-28),1,-14)); should cause a simulation error: ghdl -r resize_function ./resize_function:error: bound check failure at …

Jun 28, 2023 · I have a schematic sheet and I need more free space on it. The actual size is A4. I have right-clicked in the sheet, went to Preferences and changed the Sheet Size from A4 to A3 but that …

Sep 21, 2024 · The onboard OLED either shows a static like pattern, or full black or white depending on the resolution I try, so it seems the esp32 is communicating with it.

Oct 27, 2013 · I have heard some people talk a bit about negative resistance, but I have never really understood it. What is negative resistance?

Jun 25, 2017 · 5 I am not actually talking here about SiGe (silicon-germanium hybrids) but an integrated circuit that uses entirely Germanium (doped of course in certain areas)? It is my understanding that …
