If you have an oscilloscope and you connect the anode of the probe to either to the collector of the transistor or the anode of the capacitor, which are both common, and the cathode to ground, you will see that
If you want to control a MOSFET from for example an Arduino or Raspberry Pi, there is another thing you need to keep in mind; the current that flows into the gate when you turn the transistor on. As briefly mentioned above, the gate-to-source of a MOSFET acts as acapacitor. That mea...
Currently, the group at Fraunhofer IOF is using a PIC platform (Figure 3) from industrial quantum technology and photonics solutions provider (and project partner) Q.ANT, with 4-mode interferometers. An upgrade up to 100 modes is planned. And, to measure the number of photons coming from ea...
NVRAM uses a variety of technologies to store data. One common type of NVRAM is flash memory, which uses floating-gate transistors to store electrical charges that represent data. Another type is ferroelectric RAM (FeRAM), which uses a ferroelectric material to store information using the polariz...
Using an asymmetric output DC/DC converter such as the RxxP21509D with +15/-9V nominal outputs, if one output voltage is correct, the other can be easily post-regulated down to the desired output voltage. For our isolated gate driver power supply example, the negative rail output current ...
How to Build a Smart Lamp: This Instructable is about building your very own Smart Lamp! This Instructable will be pretty in depth and we will go over everything you need to be successful in designing and building your very own beautiful Smart Lamp
It’s still the land of opportunity, but now it’s confronting the human cost of its success. The new buzzwords: responsibility and empathy.
FET switches use a series of CMOS transistors to implement the switching. Unlike SSRs, the control circuitry drives the gates of the transistors directly instead of driving an LED. Direct drive of the transistor gate allows for much faster switching speeds because the power-on power-off time of...
Learn how to make simple boost converter circuits using transistors, and IC 555. These step up circuits will convert 1.5 V 3 V to 12 V, 24 V.
Gate Charge (Qg):The total gate charge can be found by adding the sum of the individual gate charges: Qg(total)= N * Qg(individual) Conclusion In the above post we elaborately learned how to connect transistors in parallel. We can summarize the procedure as I have explained below: ...
