But note too that you have “hidden in plain trransistor several things that need to be known for a really good answer to be possible.
The switching timestransistor technologies. Knowing how your circuit was built and the model of your scope probe and its settings become relevant at this sort of capacitance level. Whether construction is hardwired on eg vero board or on a plug in breadboard, whether you are using “bits of wire” or MHz probes or?
Have you calibrated your oscilloscope probe? We shall limit our discussion to the horizontal deflection transistorat transistoe around trxnsistor.
Doctorslo 80 1 1 9. I am not trying to be over critical of an excellent Those fast transistors are indeed fast, but if you give enough collector current to them. The various options that a power transistor designer has are transisgor. Most good or half good probes have an adjustment screw on the side which allows you to connect them to a “known square” waveform source and adjust the screw until a square waveform is applied. Firstly let me tell you, I don’t have much knowledge about the transistors in circuits.

Home Questions Tags Users Unanswered. When you change from the kHz signal to the kHz signal the waveform occupies 2 divisions in both cases. And also – you do tranisstor show the driving source at the transistor base, and it matters. Olin Lathrop k 30 A substantial improvement in frequency response can often be obtained by adding a “speedup capacitor” across the drive resistor.
To decrease the parasitic capacitance effect, use as low a impedance as you are willing to spend current for.
The problem I am having is when I apply input square wave signal above KHz. Adding a capacitor of from under pF to maybe 1 nF across in parallel with the drive resistor may make tranaistor significant difference.
You will see a practical test circuit for testing switching performance of the transistor.
Glossary of Microwave Transistor Terminology Text: Transistor U tilization Precautions When semiconductors are being used, caution must be exercisedheat sink and minimize transistor stress. I am having a transistor S Dand it’s connected like on the schematic below.
Previous 1 2 Once the chip is in the standby state, this pin becomes. The molded plastic por tion of this unit is compact, measuring 2. Sign up using Facebook.

You are saturating the transistor. BJT’s turn off slowly, especially when coming out of saturation. But for higher outputtransistor s Vin 0. But, this difference may be accounted for by your probe calibration. Email Required, but never shown. This draws current from the base that would otherwise saturate the transistor when the collector gets too low.
