ABSTRACT:
A linear voltage-to-current converter which operates entirely from a single power supply, accepts input voltages as low as one diode-drop from ground, and accepts input voltages greater than the power supply voltage is disclosed. Current mirrors sense an input voltage converted to a current through a resistor and reflect the current as one component of the output current. Additional compensation circuits provide a second component of the output current which compensates for non-linearities.
