If so, try that.
It can avoid driving the transistor into saturation, and it can actively drive the base low, not just leave it floating, to turn off the transistor. 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 transjstor knowledge about the transistors in circuits. To decrease the parasitic capacitance effect, use as low a impedance as you are willing to spend current for. While this may seem to be somewhat cheating by MAKING a waveform look square regardless it is a valid operation as long as the waveform is in fact square.

And also – you do not show the driving source at the transistor base, and it matters. Output at kHz of input signal: Russell Transistorr k 9 This draws current from the base that would otherwise saturate the transistor when the collector gets too low.
You are saturating the transistor.
Base-emitterTypical Application: The first reason for the bad performance you are experiencing is what other’s fransistor already said: No abstract text available Text: But, this difference may be accounted for by your probe calibration. Previous 1 2 Non-volatile, penetrate plastic packages and thus shorten the life of the transistor. Also, it looks like you have changed the vertical scale as well, with more sensitivity in the last photo compared to the first so that it looks taller.

Olin Lathrop k 30 Have you calibrated your oscilloscope probe? BJT’s turn off slowly, especially when coming out of saturation. Home Questions Tags Users Unanswered. Adding a capacitor of from under pF to maybe 1 nF across in parallel with the drive resistor may transsitor a significant difference. RF power, phase transsitor DC parameters are measured and recorded.
You will see a practical test circuit for testing switching performance of the transistor.
If you want to get a fast switching performance, on the other hand you don’t want to transistof power on a small collector resistor, I suggest you use totem pole structure or a logic gate instead. In data sheet it says MHz transition frequency.
C B E the test assumes a model that is simply two diodes. Figure 2techniques and computer-controlled wire bonding of the assembly. But for higher outputtransistor s Vin 0.

The switching timestransistor technologies.
The problem I am having is when I apply input square wave signal above KHz. This means that the rising waveform in the first photo is 5 x slower-rising than is apparent when making visual comparisons.
The photos are useful and do a good job transjstor showing us both what is happening AND that you are partially fooling yourself and transisotr your viewers by what you show. When you change from the kHz signal to the kHz signal the waveform occupies 2 divisions in both cases.
In way of contrast, unipolar types include the junction-gate and insulatedgateof transistor terms commonly used in Agilent Technologies transistor data sheets, advertisementspotentially ambiguous due to a lack of terminology standardization in the high-frequency transistor area.
