Commercial use is prohibited without express written authorisation from Mitch Hodges and Rod Elliott. Design a compact PCB layout with feedback taken from as close as possible to the load terminal. This voltage is usually taken from the main supplies, so for a given supply voltage, expect a little less output power. While the circuit can be and has been simulated quite readily with good results, this is no guarantee that everything will work as expected.

Customers who bought this product also bought: There is also the possibility of a failure mode very similar to second 2wk1530 when HEXFETs used in linear circuits, where V GS is usually well below the inflection point. Finally, I’d like to thank Mitch for his contribution, since it describes the issues and how to solve them in an easy to follow manner, keeping complexity to the absolute minimum in the final design example.

Figure 6 – Normalised V th Vs. Also take note that HEXFETs will require a Vbe multiplier for thermal compensation, since the negative temperature coefficient does not come into play until the device has about 10 amps through it eatasheet least for the IRFP If we look at these complementary device data sheets, we will see very different figures for current capability, on resistance, and, most importantly, gain or forward transconductance. This is why we cannot practically use a class A driver, unless, of course we use one pair of output devices.

This will cause it to get hotter, so the threshold voltage will fall further and it will then draw more current, causing it to get still hotter. That it is possible to build a valve amp to a high specification is not in doubt, but they tend to be complex and expensive. Make sure your measuring equipment is decently calibrated! Dual-channel signal input Output interface: The figure isn’t quoted, but it can be calculated using the Drain-Source saturation voltage figure provided.

Mitch has made a compelling case, but much has changed since the article was written, and there is also more information available.

It is probable that the constructor will be forced to compromise, using a significantly lower quiescent current than suggested just to maintain a sensible heatsink size and temperature. Please try again later.

If the device as a whole exhibits a negative temperature coefficient for V GSso must each internal cell. Drive the gates with as much current as possible. Make sure you check the idle current before calling the design done!

It is commonly and erroneously stated that MOSFETs are ‘safe’ because they have a positive temperature coefficient, so as a device gets hotter, its drain-source R DS on resistance increases. As it transpires, the design I was looking at was unsuitable for the intended purpose, because the quiescent current 2ak1530 to remove crossover distortion was too high to be practical.

HEXFETs operated in linear mode need to be derated from the claimed maximum dissipation, and my suggestion is that a maximum of half the rated power dissipation is reasonable. The value for R7 will depend on the linearity of the driver transistors. Further searching revealed a document from Solid State Optronics [ 3 ]where the temperature coefficient for V GS is said to be It will be noted that there are no component values supplied – this is quite deliberate, and is not an omission.

Note that this only applies if the device is used in linear mode. R DS on is actually meaningless in a linear application until the amp starts to clip, and even then only reduces the maximum output power slightly.

A compact and nicely wired PCB should datssheet distortion even further. This product is no longer in stock. I accept the Terms and Coditions. As the picture shows, the second harmonic was reduced considerably, while the fourth harmonic is below the noise floor. Match the output devices as close as possible, especially for transconductance at low values of V GS. Single module sold per unit. To balance out the nonlinear curve, we can simply cut if off where it seems too bad by using bias.

The test I ran was very simple. The large notch is at the second harmonic, and the small bump to the right is the fourth harmonic. The article is intended to describe the design process and how to work around the inherent non-linearity of vertical MOSFETs, and is not intended to be a construction project.
