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 a sawtooth waveform is generated. A sawtooth wavefrom is one in which the ...
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...
These transistors were discrete devices, meaning that each transistor was a separate device. Each one came in a little metal can about the size of a pea with three wires attached to it. It might take three or four transistors and several resistors and diodes to create a gate. In the ...
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
Using an asymmetric output DC/DC converter such as theRxxP21509Dwith +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 isolatedgate driver power supplyexample, the negative rail output current is low...

Like SSRs, FET switches are not mechanical devices. 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 swit...
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 ...
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: ...
