ABSTRACT:
Resistors may be more accurately tuned by using an external resistor and comparing the value of an internal resistor to the value of the external resistor. The value of the internal resistor may be adjusted to match the value of the external resistor. Any number of on-chip resistors may then be matched and adjusted using the information obtained with respect to the first internal resistor.
