JFET-MOSFET Power Amplifier. A lovely country with endless attraction. In the era of ’70 until the end of ’80, the audio amplifier manufacturers competed with each other offerring superior technical specifications in terms of the wide frequency response, total harmonic distortion and intermodulation distortion that under 0.01% (ranging 0.01 ...

the JFET, where the current goes to ground through a .5 ohm power resistor. The crucial test is to get the 25 volts at the output while maintaining a relatively low voltage across the JFET. We want to keep the dissipation on the JFET at less than 10 watts, and depending on the individual JFET, we should be able to manage that.

I'm pretty much a nube here, so I'm not exactly sure what makes for a good audio power JFET, but I got bored last night and found that Mouser is stocking and selling UnitedSiC power JFETs in TO-247 packages. They're making these things rated up to 85 amp and 650V. I'm too green to read the data...

The input stage is the complementary JFET differential pair, the second stage is symmetrical differential amplifier with two pairs of opposite polarity JFETs, and the output stage is a complementary source follower. The amplifier can drive loads up to 150 . So, the all-JFET amplifier can be used for various audio applications.

The basic circuits on which Erno Borbely based most of his projects are described in “JFETs: The New Frontiers, Part I and II,” published in Audio Electronics AE 5/99 and 6/99. Referring to these articles frequently, the author admits, these were the “building blocks” on which many - if not all - of his amplifiers are based. This article is the first part, as originally published …
