A novel ultra low cost window cOluparator circuit was
implemented, using logic gates and a potential divider circuit.
The circuit cost was less than lORs and it outperformed
circuits that where much costlier. Effective Window output
was obtained for sinusoidal signal having 1 MHz frequency.
This replicated a circuit having Op am ps with lOV / fLs. Hence
the proposed circuit can be conc1usively found to be an effective
replacement for the conventional op-amp based window
comparator circuit.
