means simply that one of the POINTS of this invention is to reduce or
eliminate the need for component matching! I see no limits on that
resistor's value, and presumably it could compensate for a large

You said: "Think about what that took in matched parts."
The invention says it over and over. It compensates for mismatched parts:
"It is yet another object of the present invention to provide an
"Gain error ... is readily compensated by simply adjusting input
"The system ... readily generates a correction signal to be fed back into
"To calibrate and correct for errors from junction mismatches, an
