Hello! I have square-wave signal from the generator, but it is unipolar, i.e. GND to +15V. In my application I need some negative DC offset, simply to convert unipolar signal to bipolar, but there is one and the main problem - fast pulse response needed with 50-100 nanoseconds rise and fall...
I`ve got another problem:). How to open low-side (lower) MOSFET, if the source of it connected to negative polarity power supply as follows in attachement.
Ok! I`ll try as soon as possible.
Another question: there`re voltage surges on signal rising and falling, is it can be eliminated?
(As I understood you are using Proteus?)
Thanks for attention! I increased values of resistors during the experiment. There were 10 Ohms resistors, but they were becoming too hot! Approx. 0.2-1A may be needed in this circuit.
--May be these oscillations come from the power supply unit? In ideal conditions I need to get sharp rise and...
Hello! I`ve got some problems with fast MOSFET switching. My design is high-speed square-wave pulse generator with nanosecond rise and fall times, where MOSFET acts as a switch. I`ve searched several fast-switching FETs, and found that IRF630N is really suitable for my design. It has good...
