- Figure 1. A1a, U1b, and U1c generate precisely symmetrical excitation of the A and B parts being matched. The asterisked resistors are ordinary 1% parts; their accuracy isn't critical. The A > B output is positive relative to B > A if resistor/diode A is greater th
- Figure 2. The output level (mV per 1% mismatch at Gain = 1) is not sensitive to the exact value of R1/RAB
