I have encountered a circuit whereby I could not understand how does it suppose to work.
There are 2 similar P-Channel mosfet (Vishay Si1413) which I shall termed it as Q12 & Q15.
Both mosfet have their gate connected to a single control point which means if a low is applied, both mosfet will be turned on.

Hi, I`m layout beginner.
I am just about to layout foldedcascode amp., comparator, etc... for the first time in my life.
I ask you about Stick diagram.
Is that only digital? or can use analog?
If all mosfet`s size is 1u/1u, How do you use layout technique(Multifinger, common-centroid...)? and How do I mathing?

Can you please re-post with a larger picture?
As long as you maintain the same duty-cycle, changing the frequency will not change the motor voltage until the frequency is low enough for the current to go discontinuous. Perhaps you can attach some waveforms, t

the way you have biased the circuit is right only also the mosfet is stable even through temperature changes....
i think you have to be careful in the selection of resistors and caps to be used....

Since the external mosfets are not connected, Vs pin (high side ground pin) should be connected to gnd and VB pin will have a voltage close to Vcc (12V). The Ho pin will depend on the HIN pin logic. I think you should be able to see the voltage on the scope ans it should be depended on HIN pin.

In order to have answer to your question - you need to look at the mosfet DS(data sheet)
Look for the gate capacitance parameter !
Now go back and look at the controller DS for current drive (most controller cant drive more then 2 mA) in some DS you can find cap drive parameter - VG
Now check whether the controller you are using is

You can do this using either IGBT or mosfet. For greater frequencies (ie above 30 to 40kHz), you may need to use mosfets as, as far as I know, only a few IGBTs (the newer ones by ST) can operate beyond 40-50kHz.
You need to have a controller that pulses the device at the required frequency, either a microcontroller or discrete ICs and you n

This works in common emitter mode.
Without relay, you can use BJT or mosfet, with or without isolation supply, depending on circuit configuration.

Transformers and diodes have parasitic capacitances that can have undesirable consequences. The secondary capacitances, along with secondary leakage inductance, can form a high frequency resonant circuit that is excited when the diode turns off. The resonant circuit will ring and transfer the AC waveform back to the primary.

Without a schematic the only thing i can say is that you are probably not driving the mosfet gates with a driver that can handle the charging current of the gate (or you are using a gate resistor that limits the current too much) and the mosfet is not turned off before you turn it on again.
Unless you mean that the 555 circuit is not oscillating,

I think both definitions are used. If the drain side side-wall capacitance is already considered inside the mosfet model (via the W parameter), it doesn't have to be included once more, hence the first form is used.
