Re: Cap loaded

Hi Scott,
>And if you increase the C-load beyond .6uF does the peak subside?
It looks like a pole. The pole moves down in frequency and the
peak gets higher as C is increased. Interestingly, no ringing
takes place...but the waveform starts to slew badly as it goes
from + to - starting with the top right edge of the waveform and
going -.
For instance, increasing C to 100uF...The peak occurs at 4.22Khz
and 9.18v compared to about 1v at 1Khz. With a C of 10uF, the
pole is at 13.18Khz and 4.09v. With a C of 1uF, the pole is at
36.73Khz and 1.5036v.
Is that what TIM looks like when C=100uF? The waveform on one side
just can't keep up with the actual signal? Similiar to Baxandall,
Jan 1978, Figure 2?
