Abstract
A variable voltage to current conversion circuit having a first transistor and a second transistor having bases which are supplied with differentially related voltage, a diode-fashion third transistor having a base and a collector commonly connected to the emitter of the first transistor through a first resistor, a diode-fashion fourth transistor having a base and a collector commonly connected to the emitter of the second transistor through a second resistor, a first current source coupled to a connection node of the emitters of the third and the fourth transistors, a fifth and a sixth transistors having bases connected to the collectors of the third and the fourth transistors, respectively, and emitters commonly connected to a second current source, and a third current source coupled to the connection node of the collectors of the second and the sixth transistors.
