Hello all,
Sorry for interrupting, but I have some troubles with plotting bode.
Namely, the picture below shows my oscillator( he is oscillating properly at fruequency of 14.Mhz for which I need to find the transfer function (draw a bode diagram). I need to get the transfer function of the beta...
Need alternate for oscillator with part number "SIT8008AI-82-33E-28.636360", couldn't find one.
Should be compatible with FFF (form, fit and function).
Also, it should be active and not obsolete part, it would be helpful if you can provide a link for it.
Thanks in advance.
Hello. I am new to LT spice and I am having a lot of trouble simulating a duffing oscillator. I‘ve tried changing integration methods, changing tolerances, using .startup, using .uic, and lots of other things.
I get two different errors depending on my settings (see image):
1) time step too...
I don't know much about opamps.
The idea is to use various opamps in series, with different charateristics according to the input voltage, but with the main goal to increase the peak voltage,let's 5 or more volts, and mostly keep the sine wave frequency of the orginal circuit. Is this possible...
Hello all. I'm currently trying to repair a damaged PC engine LT (a portable games console circa 1991)I got a few years ago. The thing had 10+ lifted pads and three lifted traces from corrosion from bad caps when I got it, and the first step was to clean it and repair the traces and pads as...
Hi forum.
Have this project I intended to do like 10 years ago, now I finally had found time for it. So I have this little radio controller for a toy car. Unfortunately, all but the PCB remains, and I don't remember (nor worked out) the correct DC voltage - I can only guess 9V by now.
Also the...
Hi, hopefully this is the right place to post this question. I’m looking to build an oscillator. I have all the parts ready to order and I wanted to double check that I’m not making an obvious mistake. I’m completely new to this and I thought it would be worth a second opinion to know if the...
How do I start the oscillation of a Royer oscillator in Simulink Simscape?
I'm aware of the fact that I need to manually stimulate the oscillator and I tried initiating initial conditions to the LC circuit and I tried adding a pulse in series with the dc voltage source and I tried adding a...
Sincere apologies for any ignorance I'm about to display, I'm more an artist than an engineer. If I am building a synthesizer which has multiple relaxation transistor oscillators all going into one output, running off of 9v, how I would I look into combining a MIDI input so you could control...
Hi everyone.
I've come accross an oscillator circuit (first attached image, left), which is very similar to a common collector crystal Colpitts oscillator (right).
But it is not a common collector, as the load (hf transformmer) is placed in the collector node and output is taken from there.
Not...
I bought two UJT (2N2646) before yesterday. I tried to make an oscillator but it was not working. There was a guy from FB who said it could be a duplicate (not original) one. It must be tested. How should I test if it works or not. I googled some and found about diode and resister testing. But...
Hello again,
I wanted to make an oscillator that provodes a sine wave. I don't have an oscilloscope with me but I simulated this and found that the sine wave is always at positive side. I want to make sonething that can give me half positive side and half negative side sine wave using one sided...
I provided a circuit which should discharge at a specific time. But this circuit is not working as an oscillator. How should I make circuit which will give me oscillation?
I am an electronics student and also work for a small electronics company. I have been given the task of testing 100 SMD CMOS output 10MHz oscillators to see if their resonant frequency holds true at varying temperatures. These are straight from the manufacturer and not on a board. I watched a...
Recently i started a project: trying to build my own function generator.
The most important reason for me doing this project is learning more about oscillators and their limits and possibilities.
So far i found a few designs such as the colpitts oscillator and the wien bridge oscillator.
The...
I was looking for an 1MHz oscillator for AM radio transmitter circuit. But I couldn't find one with the 4 pin crystal quartz oscillator. How to make an oscillator by myself with basic electronics materials? Any Circuit or ideas?
Is it possible to make an oscillator for AM radio with Arduino UNO R3?
What should be the code?
How am I supposed to make a full wave square wave oscillator with Arduino?
I am having trouble getting LTSpice to simulate oscillations. I drew a schematic of a simple DC source and resistor circuit to make sure I could get the software to work, and after running and adding a current waveform, the waveform displayed just as it should.
Then, I tried two oscillators: a...
what path do the holes take when the capacitor discharges?
Step 1:
I believe the the negative side of the capacitor charges through the 22R. I think the positive side of the capacitor charges through the 300K R.
At this point, the capacitor is now charged to 3v.
Step 2: the capacitor...
I have attached an oscillator circuit simulated in LTspiceIV.
Interested in knowing what kind of oscillator this is and its theory of operation.
Appreciate your explanations and comments.
Hi there
I'm struggling to get rid of jitter on my Colpitts oscillator. It is currently oscillating at 15 kHz. The problem is that I am getting cycle-to-cycle jitter of up to 384 nS. Is it possible to get a lower cycle-to-cycle jitter with this kind of oscillator. What is a typical...
I have recently been attempting to delve into the world of electronics and have been trying to build a very basic oscillator using the CD40106 chip. I have set up the circuit as follows:
9v to pin 14
pin 7 to ground
1 microfarad capacitor from pin 1 to ground
100k ohm potentiometer between pin...
hello everyone
I want to build a 50 Hz oscillator circuit using the LM324N IC,
any body have a schematics to how and what components I'm gonna need ?
thanks
I'd like to build an oscillator able to work with 12 or 24V power supply.
The output is a square wave of variable amplitude up to nearby the power supply voltage in the range of 100 to 2000Hz (precision is not an issue).
The load capability should be at least 100mA.
