Hello,
I would like to ask about the picture below:
Is there any function difference between connecting the load to pin 2 instead to pin 1 please ?
In datasheet, the manufacturer recommend to tie the load to pin 1, but for layout reason I need to bring it to pin 2.
Thaky you.
It is the S202S02...
Hello, I am here again with one more question.
Can somebody explain me the advantage of coupling transistor with gate through capacitor on the picture below, instead of tying them directly with wire? (the mentioned capacitor is pointed by arrow)
Hello. Component values are not important for this moment. I just only would like to know if I can use the Picture 2. circuit - if I can use R2 (the Source side) for BJT NPN biasing (driving). Because I have only seen the Drain side as output in all other schematics.
Many thanks.
Hello,
I am posting two pictures.
On Picture 1. is the JFET driving PNP BJT through voltage drop on R1 - this is common circuit how I found on internet by many similar variants.
On Picture 2. is the same JFET, but driving NPN BJT through voltage drop on R2 - I would rather use this variant...
Hello guys,
I would like to ask you question about following RF modules:
the first one is:
https://www.sos.sk/a_info/resource/c/pdf/tx4msil.pdf
and second one:
https://www.sos.sk/a_info/resource/c/pdf/txsawboost.pdf
First one has output power about 2 dBm and uses PLL oscillator
and second has...
Hello, I changed caps to 47pF. It works better now. The start up time is up to 2 seconds.
Thanks to everybody, especially to betwixt.
But I am confused about the oscillator´s wave shape - I supposed the square wave but I have sinusoidal wave instead.
Is it normal for such frequency please?
PIC 12 F 675 low power oscillator using 32,768kHz crystal
Hello guys,
I am using low power oscillator configuration on PIC12F675 MCU with 32,768kHz crystal.
My problem is that the program starts after approx. 12 sec from power supply switching on, what is too long time for me.
I am using 100pF...
LC oscilator type
Hello, I have queastion about type of the osclator I found on wikipedia here:
File:NPN Colpitts oscillator collector coil.png - Wikipedia, the free encyclopedia
This oscillator is described as "Colpitts", bud I compared it to another schematics of Colpitts oscilators and I...
Hello, can somebody give me advice how to calculate the power consumption of the transformer's primary choke, when no load is applied to secondary winding please?
My transformer parameters are:
primary winding voltage rate = 230V
primary choke impedance = 2000 Ohms
I just know only abut this...
