Why don't you get a 150Mhz crystal and create a transistor oscillator. Than it will be Sine wave.
According to the error message you are trying to build a ring oscillator with delay-less inverters. That's not possible.
Hello, I have a three stage ring oscillator that oscillate with 1GHz. each delay is a simple inverter. I use a tri state inverter in parallel to the first delay stage in ring structure. The frequency difference between two state of connecting and disconnecting the tri-state inverter is limited to 50MHz. Even the w/L of (...)
Your circuit is missing the important RC that sets its frequency.No. Ring oscillator does not require such RC. Cascaded inverters of odd numbers cause oscillation if a loop is configured by them due to propagation delay of inverter. So I have this 3-stage ring oscillator of which I h
Never have seen an oscillator without active elements. Since when are inverter gates or whatever forms your ring oscillator considered passive? How do you implement a 5 stage ring oscillator at only 25 MHz?
Synchronized N=5 ring oscillator as part of a PLL, pick the tap you like?
Hi, I wonder if you come up with an idea!:shock::idea: "resettable ring oscillator". Does it make sense?:bang: Would you know if it is feasible to design a resettable ring oscillator? If so, how to do it? How does it work?:razz: Best,
A ring oscillator with an odd count of inverters will always oscillate, because of the 180 phase shift. If you want to add phase shift to your Verilog-A inverters, perhaps this example could help, s. pp. 199 ff.
Its internal configuration is so that. It may be used as a inverter ( for instance ring oscillator) or anything else.,.
The phase shift oscillator is not resonant with the load (11.2 kHz Q=3 ) Can you tune the oscillator or do you prefer to resonate with the load instead.
A CMOS inverter ring will vary a lot with Vdd. About the same ratio as your IDsat (since capacitance changes not much). A bare ring oscillator can be tough to test especially at probe, the edges against bondwire or probe inductance can make the ring unstable (kill oscillation, etc.). Well designed ROs may have a high #bit counter appended to help
Usually a cheap squarewave inverter (12VDC to 120VAC or 230VAC) uses a squarewave oscillator to drive the Mosfets.
Hi all guys, I am trying to make an oscillator using CMOS inverter for quite some time and it won't oscillate at desired frequency. I want to make 125 KHz oscillator using following schematic (the element values are not relevant for desired frequency): 111933 The circuit simply won't oscilate for every combination of
A transistor needs base bias voltage and current for it to begin to turn on and amplify. A Jfet is already turned on and amplifies when it does not have any input bias voltage. There are hundreds of schematics about your Hartley oscillator in Google Images, some of them work. Some of them show the transistor with no input bias so it will not wo
hi, it's an inverter circuit which produces high voltage . Basically an oscillator driving a step up transformer (the sealed box )
I have a four terminal crystal oscillator. The four pins are: Vdd, GND, Enable, OUT The frequency output is wrt Ground. Microcontrollers have two terminals for oscillator input, and the oscillator is supposed to be connected in a floating manner across the two pins. However, since my crystal-oscillator output is wrt (...)
Hey guys. I recently found that a MCU's built in oscillator failed whenever the device went anything under 0 degrees "Celsius" The Osc worked in LOW power mode and it was at 20Mhz. When we divided the clock with anything above 2 it seemed to work fine. Now this is weird since if you divide the clock it doesn't necessarily mean that the osci
Hi all, i wonder if anyone can help me! im using proteus which ive used for a while but never really gone into the simulation side of it. Im having some trouble getting oscillators to run?! ive tried various op amp and logic gate oscillators and they just sit there showing their original state. Ive tried graphing the output and using the oscillosco
... i need the load capacitance at the output of a inverter in a 3 stage ring oscillator in a specific temperature The load capacitance at the output is the capacitance by which you load the output - so it's up to your application ;-) also i need the oxide capacitance at
I'm unsure about a question in my lab homework which the book doesn't seem to address. Maybe I'm missing something simple. The question is about a ring oscillator produced by connecting 5 of the inverters on a 74HC04 in series without a load. Vcc is 2V and the measured output frequency is 5 MHz. The question is: What is the capacitive loading
