Even falstad has a simple free PLL simulation.
You can use any good CMOS logic inverter with good decoupling. 111687 ω=(LC)e-? where C is the series equivalent of C1, C2 and allow for stray and input capacitance of a few pF.
Let me share
You can make a simple experiment with the falstad fourier series applet and visualize the effect of a 2.5 or 5 GHz bandwidth limitation and a 500 MHz sawtooth. This should clarify a basic problem of a hugh frequency sawtooth generator. Then specify your requirements, or better explain what you want to achieve. Any BJT transistor circuits base
What does these diodes do with the transistor? 110400 110401 Why dont you use a sweep signal on circuits using Analog Circuit Simulator under . You can choose any design then modify by adding components and wires
falstad's animated simulator has a memristor model. Free to download and use at: Screenshot of a sample circuit, showing edit window with parameters for the
I would do
there a java based tool called falstad try simulating the circuit with that.
try this
In case a simulation will be informative... Here is a screenshot of the Tesla coil schematic included in falstad's animated circuit The spark consists of several sparks, resulting from resonant actio
You can drive any simulator with a series resistance of choice like 50R and then adjust bias until input is 50% or in other words R in= 50R. For hFE=200, @5V Rb= 9~10k and ditto with the Load. Thus for Rb=9.5k Zin = 50 Ohms and Zout=200 Ohms with same load,
Another method of measuring the real impedance inputs and outputs is to measure the no load and 50%V load resistance. On this device simulator, the impedance turned out to be near 500 Ohms for maximum power transfer with very high gain on small sig. (1mVp) go here and import this (C
See my posts in this thread: They contain links to my simulations of buck, boost, and buckboost converters (laid out in falstad's interactive animated simulator). Scope traces show updated specs on various components. You can observe specs moment to moment. Just hover the mouse over a component, node
I sometimes get the 'singular matrix' error in falstad's simulator. It is a vague message which might have any number of causes. In a real circuit it would not necessarily prevent operation. I've found I must try numerous tricks to get around this error. * Avoid placing two capacitors in series. Install a resistor in series with one of the ca
falstad's simulator will do what you want, or something like it. Free to download and use at . As you can see, the scope trace depicts the frequency sweep over time, and the inductor's response. (The Henry value does not change unless you apply unusual conditions.) The right-hand lissajous figure indicates phase changes
Here is a memristor circuit included with falstad's simulator (it includes 7 total). The specs window is If you click the link below, it will open the website load the schematic into his sim
Clicking this link will open the website , load my schematic, and run it on your computer. To re-run the simulation, click the Reset button. When you click Export a window opens containing the data file. I do not believe it is in Spice format.
In falstad's simulator I make the AC voltage +- 0.45. I add 1.35 V DC produces a crest at 1.8 V, and a trough at 0.9V (as shown by the scope readouts). I don't know if this will work in your program.
Say, funny you would mention java applets. Check out falstad's simulator. It's animated and interactive. See the Circuits menu for an assortment of seven PLL related circuits. Here's a screenshot of the Type 2
use an NPN transistor (bjt) with a base resistor to invert the logic. something like this --
