Hi, Im working on the design of a Voltage controlled oscillator for a synth. I need a voltage-current converter circuit that will convert a voltage range of about 1V-2.5V linearly to about 1mA-10mA.
Any suggestions? Ive been playing around with a circuit involving an opamp, a couple of resistors and 2 transistors, but i cant seem to get the current output to change linearly with the voltage input.
Thanks a lot.
Sam
