Controlling the frequency via voltage is the best method by using Varactor diode or the Varicap diode even you can divide the frequency easily and it's stable as I remember in 90's we were doing that type of circuits
Great Video. How do I find more information on the output capabilities of an RF oscillator. Is there an output voltage? power output? Do you not think of oscillators like you would a normal circuit?
Thanks for the video especially the specification part! I came across to test a Oscillator product as a test engineer, but I want to test the squegging of the oscillator, do you mind sharing if you're familiar with the methodology of this specification?
You explain the concepts really well. Thus making it very easy to understand the concepts. I would like know to if you have come across any phase noise models for PLL/VCO which can be used to predict the levels and characteristics of phase noise. If yes, kindly share it with a video/documents about them. Thank you!
This is awesome. I was just wondering about this yesterday after browsing online and looking at various active crystal oscillators. So a TCXO is a VCO with a circuit that compensates for temperature. Are there TCXO's that have additional VCO type adjustments? Is that considered a "VCO with temperature compensation," a "TCXO with voltage control," or is there some other mnemonic I haven't heard of yet?
Yes, TCXO is the temperature compensated Crystal Oscillator. As far as I know, they do not have any additional arrangements for the frequency variation using the voltage. They are meant to provide the stable frequency irrespective of the change in the temperature. On the other end, in VCXO (Voltage Controlled Crystal Oscillator), the micro tuning of the frequency is possible ( ppm level) with the change in the control voltage.
@@ALLABOUTELECTRONICS Thanks for the reply. A few hours after commenting here yesterday I was browsing AliExpress and a listing popped up for a VCTXO. Of course there was no datasheet or reference information, but it got me searching further. One of the first search results was from a company called Connor Winfield. They have several product lines of VCTCXO oscillators. Based on a quick skim over other search results it looks like one application for these crystals is probably cellular phones. It makes sense to me. A very precise radio with extremely demanding environmental temperature conditions seems like it could benefit from such a product. All I know is that my oscilloscope is my most accurate frequency measurements device, so messing with precision frequency devices like a VCXO is entirely pointless. I still like learning about them though. BTW I'm subscribed to over 1k people here on YT. Over half of them are electronics related. There are a lot of people doing similar content as you, but they don't quite do it as well. Your presentation style and content length are perfect for me to watch casually. It's one of the few I watch regularly. I just want to say I appreciate it, and thanks. You're doing a Iittle bit to help me, some random disabled person in California, to stay busy, learn something, and make better use of his time. Thanks.
Explained very well..Now this is my fav classroom. Sir, can you tell how can we set High level and low level to the output of a pulse generator? I tried clamping circuit. But it's not working with that.
but the frequency is inversely proportional to the product of resistance and capacitance and not to the square root of the product of resistance and capacitance....
Hi! I would like to know if VCO can amplify the frequency of an input signal. So I have an oscillating input signal and I want to increase its frequency. Is it possible? If not, is there another option to do so?
There are many actually. depending on the range, you can select. For example, for 40 MHz to 650 MHz range, you can use MAX 2605 - MAX 2509. Each covers the different range. For example, MAX 2605 covers 40 MHz to 70 MHz, while MAX 2509 covers the range from 500 MHz to 650 MHz. These VCOs are based on the Colpitts Oscillator. You need to connect the external inductor. the values of each range is given the datasheet. You can check the mouser website and search for the specific VCO. You can use filter option to choose the specific VCO.

This is a brilliant video! It explained what all those books couldn't!
The best channel on TH-cam to learn electronics theory!
No, far from it. If you listen to this style of and nature of delivery for too long, you'll turn into a robot.
@@ryanchan8583 YEAH! This guy isn't explaining anything just reading out from somewhere.
Among my favourite teachers. Thank you very much for the video.
EXCELLENT 👍👍 AS USUAL
Love your channel
very very thanks bro... Thanks for ur help in learning about these inthegrated circuits
Can or will you do a video about PLL? Thanks.
Yes, very soon.

Let say the tunning gain is 1MHz/V what does this mean the steps also gonna be per volt or something else
Explained very well..Now this is my fav classroom.
Sir, can you tell how can we set High level and low level to the output of a pulse generator? I tried clamping circuit. But it's not working with that.
Do you mean the amplitude of the waveform ?
Im searching for multiple videos for info-

Please make vedio on communication system
Phased locked loop used frequency divider video please
Very soon it will be uploaded.
fantastic
but the frequency is inversely proportional to the product of resistance and capacitance and not to the square root of the product of resistance and capacitance....
Sir pls make a class on feedback 🥺
Hi! I would like to know if VCO can amplify the frequency of an input signal. So I have an oscillating input signal and I want to increase its frequency. Is it possible? If not, is there another option to do so?
Using Phase Lock Loop (PLL) it is possible to do that. Please check the video on PLL, I have already explained it in that video.
@@ALLABOUTELECTRONICS thank you so much! I'll do it 😉
Sir Pin Diagram Of Voltage Controlled Frequency And Astable Multivibrator Are Same ??

No, it will be different.
