Depends upon the perception of "modify". You have to replace the linear
current source of the A-132-1 by an exponential type (one operational
amplifier, two transistors and a couple of resistors and capacitors). In any
case electronic experience is necessary. Or you look at the A-132-3 which
has two VCAs that can be switched to linear or exponential.
