If the XR is dead, I need an alternative discrete circuit. Thread starter Speakerguy Start date Jul 16, Speakerguy Active Member. Any help is appreciated!!! Last edited: Jul 16, Square wave is fine for now for FM modulation of course. I want to shift the output away and towards the output to get an amplitude modulated signal on the secondary.

Any harmonics will be way above resonance and contribute little to the output hopefully. I'm also looking at the LM to see if it would work.

It's precision is really high. A 20khz audio signal can FM modulate a 30khz carrier with a deviation of 1khz. In theory. However in practice, there will be spectrum components at 10, 30 and 50 khz which in this case the high Q 30khz resonant transformer will filter out.

Result - no modulation. If you AM modulate the 30khz carrier with 20khz audio, there will be spectrum components at 10, 30 and 50 khz, and again the high Q 30khz will attenuate them and filter them out.

Again result is no modulation. I'm using COTS parts for this right now. Custom stuff will allow for higher frequencies. Ubergeek63 Well-Known Member.Latest Projects Education.

I'd prefer not to use the to produce the ramp; I've tried several schemes and the results don't satisfy. I'd prefer to use a chip like very much I used it some year ago and the result was very good in term of THD.

I've read in the web that the has been obsoleted by the producer Exar. So I wonder, and asking you, if there's a good alternative to that chip which is as cheap and as easy to implement. Re: Oscillator: alternative to xr You're welcome. Google "function generator IC" and you'll get a few more. I picked the Maxim because it seemed simpler to use than say, the Analog Devices part. Test equipment, replica and original sci fi props and costume pieces, and whatever else I feel like at the time.

I have an Ultimaker and a 3D engraver. Except that the MAX is being discontinued. However, you can still buy the chips on eBay. Just in case you need a design that you can make more of. Some versions may be No Longer Available or being discontinued and subject to Last Time Buy, after which new orders can not be placed. What types of circuits have you tried?

A current mirror is a simple way to provide the constant current for charging. A schmitt trigger and an integrator two Op Amps also make a handy triangle wave generator. Thank you all guys. Polimorph, I've tried a circuit with without active current source and the sawtooth shape was curvy too curvy the raising ramp, and the falling one too smoth. Sure, the RC charge curve is asymptotic, so it won't be linear. I've found the constant current source works very well for making a linear sawtooth.

Use identical PNP transistors, preferably from the same batch.Forums New posts Search forums. Articles Top Articles Search resources. Members Current visitors. Log in Register. Search titles only. Search Advanced search…. New posts. Search forums. Log in. Welcome to our site!
