ABSTRACT:
The present invention includes at least two variable-resistive devices, such as transistors, coupled to a resistive device, such as a resistor. The transistors are configured so that feedback voltage generated by respective currents of the transistors is applied to the gate of at least one of the transistors. The electrical characteristics of the other transistor changes proportionately greater than the characteristics of the one transistor. With this configuration, a variation-compensated current device is provided.
