ABSTRACT:
A linearized resistor for integrated circuits combines an N-type diffused resistor and a P-type diffused resistor. In one embodiment, the N-type and P-type diffused resistors are connected in series. In another embodiment, the N-type and P-type diffused resistors are connected in parallel. Two or more linearized resistors of the present invention may be used in IC circuits, such as voltage dividers, inverting amplifiers, single-ended operational amplifiers, and single-ended differential operational amplifiers. Linearized resistors of the present invention can be designed to have voltage coefficients smaller than conventional IC resistors having a single diffused resistor. As such, linearized resistors of the present invention can be designed to provide more uniform resistance over their operating voltage range than conventional IC resistors. As a result, linearized resistors of the present invention can be used in differential circuits that are more effective in reducing odd and even harmonics than are conventional differential circuits.
