Abstract
A microcircuit resistor stack, which comprises of at least one set of equal value resistors connected in series providing a course trim, the at least one set of equal value resistors having at least two resistor; and at least one wirebond configuration, the at least one wirebond configuration being able to provide the fine resolution trim of the resistor stack.
Claims12
A microcircuit resistor stack, which comprises:
- (a) at least one set of equal value resistors connected in series providing a coarse trim, the at least one set of equal value resistors having at least two resistors;
- (b) at least three contacts, one each on ends of the at least two resistors, and one between the at least two resistors, serially connecting same;
- and
- (c) at least one wirebond configuration, the at least one wirebond configuration being able to provide the fine resolution trim of the resistor stack, the at least one wirebond configuration electrically and physically connected to the at least one set of equal value resistors, the at least one wirebond configuration completely crossing over at least the contact between the at least two resistors.
