comparatorín
Comparatorín is a term that appears to be a portmanteau of "comparator" and the Spanish diminutive suffix "-ín". A comparator is a device or circuit that compares two input signals and outputs a signal indicating their relative magnitudes. The diminutive suffix "-ín" in Spanish is often used to denote something small, cute, or less significant.
Therefore, "comparatorín" would likely refer to a small-scale or perhaps a simplified comparator circuit or device.
