"Anthony Fremont" wrote in message I have never seen clipping. These things are supposed to limit in cutoff, not saturation. As the signal build up, the conduction angle gets smaller and smaller until the device runs out of gain. That is another way of saying that the DC value of the gate voltage gets more negative the bigger the amplitude. This works out automatically with a JFET. You need about 10K - 100K DC resistance from gate to ground. Using a bipolar transistor is not a good idea. I was wondering about the load that a bipolar would present. I will see if I can find a JFET in my junk pile, thank you. :-) |
