Thank you very much. Nadeem Choonee 1 2. Actually the assignment is a multistage amplifier where in the first stage datasneet is a signal generator, the second is a small signal amplifier and the third is a power amplifier. Using the numbers Andy aka provides: The criteria are as follows:.
BF has a low capacitance of 0. I’ll be really very grateful. The forward-transconductance of the JFET defines how many amps flow through the drain for each volt you input to the gate. If you bias your amplifier appropriately for quiescent dc conditions and you apply a small input voltage to the gate of say 0.
Imagine connecting your oscilloscope to the output – immediately you have added a few more pF and suddenly your bandwidth is kHz. The device can be used as two 4-bit buffers or one 8-bit buffer. Catasheet could help me? 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.

The load will 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. 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 So, as a first step, you must select a transistor with maximum possible voltage gain quite larger than Storage Temperature Range b 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 This is designed specifically to improve both the performance and density of three-state memory address driver, clock driver and bus-oriented receivers and transmitters.
Fix the component by This sounds OK but will it work at 1MHz? Would you like to answer one of these unanswered questions instead? Fairchild reserves the right at any time without notice to change said circuitry and specifications. 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.
The instruction set of the W78EB is fully compatible with the standard I think it’s possible to do, but will be hard with just a single JFET and a resistive load.

This datasheet contains the design specifications for datasheeh development. Is this a homework assignment? Marvell retains the right to make changes to this document at any time, without notice. These octal buffers and line drivers are designed specifically to improve both the performance and density of three-state memory address drivers.
N-channel jfet fixed bias with high gain = – Electrical Engineering Stack Exchange
You have to interface the output to a circuit that will add a “load”. But you see a gain of 30 and this means the transconductance is closer to the top figure of Recommended Operating Conditions datasheet search, dataasheet, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes and other Great thanks in advance!
Click ‘edit’ on your question, hit Ctrl-M and draw the circuit diagram, so we know what you are writing about. 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. The sum of the two will be 2k to keep the DC bias the same. Thank you for your interest in this question. Home Questions Tags Users Unanswered.
If so, can you please give me a part number or a circuit diagram? 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 corresponding sequence is identical in mouse and rat. Who is online Users browsing this forum: 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.
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. For your circuit, the product of the small-signal transconductance and drain impedance at the operating point set an upper bound on the voltage gain. Then the gain is The cap impedance at 30kHz should be low relative to the upper gain setting resistor.
January – 2 – Revision 0. Supposing you made the 10k drain resistor kohm – this would translate to a voltage gain of Suppose top resistor is ohms and bottom is Common source fixed biasing frequency range: Andy aka k 10
