ODP: Retriggerable VC One-Shot?

[Roman Sowa]

An integrator, say 10nF, drain 100nA with current source (or 10M res. from
-1V)
reset the cap with trigger edge using differentiating RC network and FET
feed integrator output to comparator (-). Put CV on (+)
10mV gives 10ms, 10V gives 10s.
It may be difficult to obtain good performance at short-time end.

hope it helps
