The mid point of the resistors should have a cap to GND.

Suppose top resistor is ohms and bottom is These octal 2n381 and line drivers are designed specifically to improve both the performance and density of three-state memory address drivers. Supposing you made the 10k drain resistor kohm – this would translate to a voltage gain of Will be grateful for any help!


This datasheet contains the design specifications for product development. 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. The 2N it has a typical value of about but, according to the Fairchild data sheet this can be as low as or as high as Who could help me?

The load daatsheet likely hurt the circuit performance above kHz but the biggest problem I think you face is finding a JFET with an output conductance of less than 5 uSiemen equiv. Output Conductance is quoted at 50 micro-siemens and when translated to output resistance this is 20k ohm. Click ‘edit’ on your question, hit Ctrl-M and draw the circuit diagram, so we know what you are writing about.

This sounds OK but will it work at 1MHz? I think it’s possible to do, but will be hard with just a single JFET and a resistive load.

Home Questions Tags Users Unanswered. Using the numbers Andy aka provides: The criteria are as follows: BF has a low capacitance of 0. Fri Sep 25, 8: If so, can you please give me a part number or a circuit diagram?

The answer is “no” because, the jfet has parasitic capacitances that will severely take advantage of such a high value resistor in the drain. January – 2 datashdet Revision 0.

But you see a gain of 30 and this means the transconductance is closer datashee the top figure 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.

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.

The instruction set of the W78EB is fully compatible with the standard The sum of the two will be 2k to keep the DC bias the same. Great thanks in advance! The cap impedance at 30kHz should be low relative to the upper gain setting resistor. Alfred Centauri 24k 1 15 Is this a homework datasheft
