I appreciate you sharing your work and am ...Diego,<br /><br />I appreciate you sharing your work and am interested in some of the JFET work you are doing here. <br /><br />Your comments on J201 SPICE models are very interesting. I have designed a buffer to use for a variable resonance onboard guitar tone control. You might find this interesting. Here's the Circuitlab URL:<br /><br />https://www.circuitlab.com/circuit/64c7by5tsurb/discrete-buffer-j201-v1/<br /><br />Basically I can't use a simple JFET buffer because I need a low output impedance and a simple buffer will draw too much current from the battery in this case. So the approach is to use a "Borbely follower" with 2 JFETs. This is Erno Borbely's take on the White cathode follower.<br /><br />The variable resonance tone control is described in three posts on the Music Electronics Forum. Here's the URL for the first post which contains links to the two other posts. <br /><br />http://music-electronics-forum.com/t43081/<br /><br />I would appreciate any design input you would have, also if you had SPICE models that are accurate for both the MMBF4117 and MMBFJ201 that would be a great help.<br /><br />Thanks,<br /><br />Charlie Richardson<br />charrich56@hotmail.comAnonymoushttps://www.blogger.com/profile/16217878927807559352noreply@blogger.com
