Abstract:
System and method are provided for generating a plurality of channel currents. The system includes a channel reference generator configured to receive a first reference current and generate at least a first channel driving current and a second channel driving current, a first channel current divider configured to receive the first channel driving current and generate a first input current, a second input current, and a third input current, a second channel current divider configured to receive the second channel driving current and generate a fourth input current, a fifth input current, and a sixth input current, a first channel driver configured to receive the first input current, the second input current, and the third input current and generate a first channel current, and a second channel driver configured to receive the fourth input current, the fifth input current, and the sixth input current and generate a second channel current.
