I am trying to design a Common Collector but I have 2 problems:
1. The negative part of the ac signal is clipped unless I use a very high dc voltage (such as 100V).
2. The circuit only works fine at high capacitances.
Here's a copy of the circuit
http://forum.allaboutcircuits.com/attachment.php?attachmentid=8527&stc=1&d=1238940076
By the way, are there any rules of thumb for this type of circuit? I used the R2= (beta * RE) / 10 but I'm not sure whether it is valid since there is no RC.
Thanks
