Hi
 I'm not sure if I understand your question. You simply
change the time constants to be in the range you are looking
for. If the original used a 10K and it was 0.1 seconds,
using a 100K will make it 1.0 seconds. The capacitance
values scale similarly.
 Do remember to remodel things so that the equation
is all integrations and no differentiations. Doing
integrators is preferred for these problems.
 I don't think you change the gains unless you want
different responses. You only change the time constants
so that you can watch the response. Of course, each
step is linear so that you and divide at the input of a
stage and the multiply the output if there is a compliance
issue. Otherwise, just control the size of your stimulus.
