Novel method to compensate for resistor non-linearities and its application to the integration of analog functions on system-on-a-chip ICs

A compensation method is demonstrated which corrects nonlinearities in resistors. This is accomplished by measuring the resistor's nonlinearity and compensating for it through a feedback loop. An improvement of greater than an order-of-magnitude is shown. This technique is useful for the integr...

Description
Summary:A compensation method is demonstrated which corrects nonlinearities in resistors. This is accomplished by measuring the resistor's nonlinearity and compensating for it through a feedback loop. An improvement of greater than an order-of-magnitude is shown. This technique is useful for the integration of analog circuits on system-on-a-chip ICs, where a purely digital microfabrication process, containing no linear resistors, is used.
