Hi, Im having trouble with a voltage controlled oscillator circuit that im trying to get going. basically the only thing that is holding me back, is I need to somehow convert an input of .25V to a minumum of 70mA to charge a capacitor.
the V/I converter must be linear, so the current has to increase from 70mA - XmA as the voltage increases from .25V - 7V.
This is my first major project, and im not that good with electronics. any suggestions would be much appreciated, because im starting to lose my mind trying to get this VCO going.
Thanks a lot.
