Volts to Current problem

[Paul.Maddox at bew.co.uk]

Dear All,

	I have a question. If I want to control
a current from a voltage how woudl I do it?
A the moment the circuit I have has two resistors
controlling the PW of an OSC (8038) if I want
to change the width I have to decrease one and 
increase the other. How do I do this with a a single
CV?. My theory was two opamps (one inverting the
signal and one not) driving (via a small resistor)
the two I/P pins on the 8038 therefore controlling
the current into these... Is this a Bad way? Is there
a Much neater way?
	Could I find a voltage controlled resistor?
could a FET be used and if so how?
	

	Please help.

	Paul Maddox
