TRANSISTOR MATCHING FOR GENERATION OF PRECISE CURRENT RATIOS

Systems and methods are provided for generating accurate current ratios from a current mirror including an array of output transistor and a corresponding array of switches. Each switch couples in series with its corresponding output transistor. A control logic circuit controls the switches to cancel...

Summary:Systems and methods are provided for generating accurate current ratios from a current mirror including an array of output transistor and a corresponding array of switches. Each switch couples in series with its corresponding output transistor. A control logic circuit controls the switches to cancel mismatches for the output transistors.
