  • IC precision resistor ratio matching with different tub bias voltages
    Patent number: 5757211
    Abstract: An integrated circuit motor controller having two or more integrated resistor dividers which produce signals to be compared with each other is disclosed. The circuit is designed to substantially reduce the dependency of the comparison on the reverse bias of the junctions between diffused resistors in the integrated resistor dividers and the silicon into which they are diffused.
