Diode ladders vs. single leg
I've been trying to figure out why one would use a ladder instead of a
single leg. Here's a difference:
In a ladder, when the control current changes and the diodes are
matched, there is no resulting transient current through the
In a single leg filter, the caps need to charge/discharge when the DC
operating point changes.
Now, is this significant? If a step is applied to the control
current, the voltage will step as well, but with less amplitude
(logarithmic) and filtered through the capacitors. Guessing it will
still sound like a filtered discontinuity, i.e. ring at high
EDIT: This is a very clear pop. Annoying to the point of being
useless. How to remedy?
