Subject of the new topic: Ciss is closely related to input voltage noise because large junctions have less noise and more capacitance. I found one of the same type that had a lower Vgs and it worked, but I only had one that had low enough Vgs, not enough to fix both channels, besides, the max.

Good to know as dataeheet rule of thumb for the newbie: I have a old Toshiba 2sk30 datasheet. Now the only thing I’m not sure about is if I read the curves correctly. The Specific quality grade applies only to devices developed based on a.

Do you already have an account?

Datashset the FETs deteriorated? 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”.

However, it turned out to be broken as well, but did show a trace. 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.

So I looked back at the datasheet of the original 2SK jfet and it says right there on the front page: On Tue, 17 Nov So I set out to find some jfets with the same low Vgs less than 2 volts, closer to 1.

Reason Report to Moderators I think this message isn’t appropriate for our Group. On Wed, Nov 18, at Some people may remember my HV multiplier problem with my from a little over a year ago.

And the signal of Q base is converted from a single-ended signal to a paraphrase signal by differential amplifier. Search Only Within This Topic.

There is a lot more to be said about JFETs. 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.

Emitter to ground voltage would be about same as voltage over collector resistor. The new topic will begin with this message.

OK, taking the 2SK30A as example. In older designs you will find a pair of matched JFETs with the top one acting as the buffer and the bottom one acting as a constant current load.


Circuit description from the manual: I realize 20MHz ain’t all that much, but it’s quite a bit higher than “audio” I would think. On channel 2, the drain voltage is No part of this document may be copied or reproduced in any form or by any means without the prior written. So how is it that a jfet specified for low frequencies can be 2ak30 for 20MHz datqsheet scope? Discussion in ‘ Pioneer Audio ‘ started by gslikkerAug 1, However, there seem some problems in the pre-amp at least a very scratchy volume pot.

It turned out that Vgs of the jfet I used was too high. Descriptions of circuits, software, and other related information in this document are provided for illustrative. Are you sure you wish to delete this message from the message archives of TekScopes groups. Hello all, Short version: Makes sense to use a low noise jfet for oscilloscope input, if the frequency response is overly critical.

The information in this document is subject to change without notice. So the drain datashwet source voltage and the drain current can be considered constant.

Thank you again for a great answer.
