The incorporation of these circuits. Circuit description from the manual: When I got them in, and was trying to decide whether to use the 2SK30A or the 2SK first I discovered that they’re both for “audio frequencies”.

Typically the constant drain current will be 5 to 10 milliamps and from that it is possible to lookup the Gm which is what I did. So I have decided to check it out totally and do whatever necessary to make it work flawlessly. On channel 2, the drain voltage is Rising edges of square waves are nice and vertical.

On Tue, 17 Nov This cannot be undone. I found a couple and datashewt two types: On Wed, Nov 18, at 9: The recommended applications of.

Thank you again for a great answer. Emitter to ground voltage would be about same as voltage over collector resistor.

Vertical input designs where the input can vary over a wide range like with differential amplifiers take special steps to maintain a constant drain current. Before using this document, please. For a 20 MHz oscilloscope, it would be difficult to find a small signal JFET which is too slow and that is why it worked. There are several curves plotted, should I measure Vgs off for a particular jfet and then use the curve that starts at datzsheet Vgs off voltage?

I can find different gm values on this plot. I read about the design, dont remember where, of the input amplifier to the Tek scope.

NEC – datasheet pdf

The gain is close to unity and therefore the JFET is not very demanding when it comes to frequency range. You can look for “Vertical Amplifier Circuits” by Tektronix. The Specific quality grade applies only to devices developed based on a. However, there seem some problems in the pre-amp at least a very scratchy 2k30 pot.

Share This Page Tweet. Discussion in ‘ Pioneer Audio ‘ started by gslikkerAug 1, Searching the datasheet I stumble over other satasheet, without graphs of this FETs behavior.

From the datasheet http: Are you sure you wish to delete this message from the message archives of TekScopes groups. Ian van der Neut. While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices. I 2k30 not think that there is anything wrong, the two jfets do not have the same Idss, so the bias will vary.

Log in or Sign up. Now, I would like to hear the experts evaluation of this SA control amp schematic. So how is it that a jfet specified for low frequencies can be used for 20MHz bandwidth scope? When excessively high-amplitude signals are applied to the source follower, the signals will be Q and the gate-source junction of Q No license, either express, implied or otherwise, is granted under any patents, copyrights or other. Some day I’ll figure it out: Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life.

Newer designs use a low input bias current operational amplifier in place of the bottom JFET however while this allows for better offset drift with temperature, they will usually have worse overload recovery. I could not find any graphs about this 2SK30Y behavior Now, as the schematic calls for a suggested drain voltage of 6.

Your email is included with the abuse report. So the drain to source voltage and the drain current can be considered constant. Close to Alkmaar, Netherlands. Through a sine wave in there and see if you are getting symmetrical clipping. It was far more complex than I first imagined it to be. Makes sense to use a low noise jfet for oscilloscope input, if the frequency response is overly critical. Whereas I will be soldering at the board anyway, guess I mount tiny small transistor sockets and experiment a bit using several fets to get myself comfortable working with these.

If customers intend to use NEC devices for applications other than those specified for Standard quality grade. Even Fairchild made a ksk30, y grade has a Idss of 1. On Tue, Nov 17, at 2: The Group moderators are responsible for maintaining their community and can address these issues.
