Revised Stage 2: Non-Saturating Active Maximum Selector (for positive voltages)

Explanation (This is a simplified representation of a known non-saturating Max circuit. Values and specific internal connections might vary slightly depending on the exact variant):

This class of circuit leverages summing and differencing. The key is that the op-amps remain in their linear region.

OpAmp_MAX_A & OpAmp_MAX_B: These act as individual processing stages for each input.

OpAmp_FINAL: This combines the outputs of the previous stages to produce the maximum.

The exact resistor values and topology for R_A, R_B, R_C, R_D are critical to ensure that the sum of the inputs and outputs correctly resolves to the maximum value while keeping all op-amps within their linear range.
