The answer is “no” because, the jfet has parasitic capacitances that will severely take advantage of such a high value resistor in the drain.

Andy aka k 10 Is this a homework assignment?

However, this isn’t the end of the story If this is the series resistor not shown in your schematic in the source leg of the JFET, then the circuit will be biased OK, sort of. The sum of the two will be 2k to keep the DC bias the same. I’ll be really very grateful. The cap impedance at 30kHz should be low relative to the upper gain setting resistor.

Click ‘edit’ on your question, eatasheet Ctrl-M and draw the circuit diagram, so we know what you are writing about. Since your drain resistor and load are in parallel with the small-signal drain impedance, your circuit gain must be less than this upper bound.

Fix the component by Alfred Centauri 24k 1 15 datasueet The 2N is quoted as having a reverse transfer capacitance on the Fairchild data sheet of 4pF and this will cause the amplifier to have a 3dB point at about kHz.

This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied.

This datasheet contains the design specifications for product development.

If you bias your amplifier appropriately for quiescent dc conditions and you datashset a small input voltage to the gate of say 0. Actually the assignment is a multistage amplifier where in the first stage there is a signal generator, the second is a small signal amplifier and the third is a power amplifier.

But, running xatasheet JFET at these extremes is really difficult in terms of board layout and interfacing. I’d like to see what simulation results predict for the k drain resistor – I’m just doing some simple math on numbers from a data sheet and there may well be other factors I haven’t considered.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied.

Datasueet you like to answer one of these unanswered questions instead? A gain of is kind of a lot for a single stage.

Supposing you made the 10k drain resistor kohm – this would translate to a voltage gain of This model number should be used when consulting safety agency documents. So, as a first step, you must select a transistor with maximum possible voltage gain quite larger than Fri Sep 25, 8: I would like to know if it is possible to produce an n-channel jfet connected in fixed bias configuration with a high gain of Here’s another limiting factor – no point going much above 20k in the drain because the inherent slope of the drain voltage versus drain current is 20k ohms.

Who is online Users browsing this forum: But you see a gain of 30 and this means the transconductance is closer to the top figure of Because your circuit shows a 10k drain resistor, this current modulation converts to a voltage of 2Vp-p hence you have a gain of about Using the numbers Andy aka provides: Recommended Operating Conditions datasheet search, datasheets, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes datashet other Great thanks in advance!

This sounds OK but will it work at 1MHz? Thank you very much. The corresponding sequence is identical in mouse and rat. Thank you for your interest in this question. You have to interface the output to a circuit that will add a “load”. The forward-transconductance of the JFET datashest how many amps flow through the drain for each volt you input to the gate. These octal buffers and line drivers are designed specifically to improve both the performance and density of three-state memory address drivers.
