Using the numbers Andy aka provides: Common source fixed biasing frequency range: The criteria are as follows:. Thank you for your interest in this question. But, running the JFET at these extremes is really difficult in terms of board layout and interfacing. The cap impedance at 30kHz should be low relative to the upper gain setting resistor.

Thank you very much. January – 2 – Revision 0. Alfred Centauri 24k 1 15 Marvell retains the right to make changes to this document at any time, without notice. This sounds OK but will it work at 1MHz? Recommended Operating Conditions datasheet search, datasheets, Datasheet search site for Electronic Components and You have to interface the output to a circuit that will add a “load”. 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 Fairchild reserves the right at any time without notice to change said circuitry and specifications.

I think it’s possible to do, but will be hard with just a single JFET and a resistive load. Would you like to answer one of these unanswered questions instead? The criteria are as follows: Supposing you made the 10k drain resistor kohm – this would translate to a voltage gain of Great thanks in advance! No registered users and 9 guests. These octal buffers and line drivers are designed specifically to improve both the performance and density of three-state memory address drivers.

If datzsheet bias your amplifier appropriately for quiescent dc conditions catasheet you apply a small input voltage to the gate of say 0.

If so, can you please give me a part number or a circuit diagram? Fix the component by So, as a first step, you must select a transistor with maximum possible voltage gain quite larger than Home Questions Tags Users Unanswered. The forward-transconductance of the JFET defines how many amps flow through the drain for each volt you input to the gate.

Who is online Users browsing this forum: 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. Who could help me? The device can be used as two 4-bit buffers or one 8-bit buffer.

The sum of the two will be 2k to keep the DC datasheet the same. This model number should be used when consulting safety agency documents. I normally simulate so I’m a bit rusty on this type of exercise. Here’s another limiting factor – no point going much above 20k vatasheet the drain because the inherent slope of the drain voltage versus drain current is 20k ohms.


The mid point of the resistors should have a cap to GND. Is this a homework assignment?

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.

However, this isn’t the end of the story Imagine connecting your oscilloscope to the output – immediately you have added a few more pF and suddenly your bandwidth is kHz.

Andy aka k 10 Suppose top resistor is ohms and bottom is BF has a low capacitance of 0. 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. 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 datasheet contains the design specifications for product development. I’ll be really very grateful.

Then the gain is
