ABSTRACT:
A current-splitting network comprises a voltage divider having first and second output terminals, the potentials at the first and second output terminals having a predetermined ratio. A first amplifier is coupled between one end of a first resistor and the first output terminal for holding the potential of the one end of the first resistor substantially at the potential of the first output terminal. A second resistor has a resistance value which has a predetermined ratio to the resistance value of the first resistor, and a second amplifier is coupled between one end of the second resistor and the second output terminal to hold the potential of the one end of the second resistor substantially at the potential of the second output terminal. A constant-current source is connected in common to the other end of the first and second resistors such that a constant current fed from the constant-current source is split to flow through the first and second resistors. This current-splitting ratio is determined by the ratio between the resistance values of the first and second resistors and the ratio between the potentials at the first and second output terminals.
