Abstract In this work, we investigate the interplay between correlated disorder and hopping dimerization on bias driven circular
current in a loop conductor that is clamped between two electrodes. The correlated disorder is introduced in site energies of the
ring in the form of Aubry-Andr\'e-Harper (AAH) model. Simulating the quantum system within a tight-binding framework all the results
are worked out based on the wave-guide theory. Unlike transport current, circular current in the loop conductor can get
enhanced with increasing disorder strength. This enhancement becomes much effective when hopping dimerization is included which is
taken following the Su-Schrieffer-Heeger (SSH) model. The characteristic features of bias driven circular current are studied under
different input conditions and we find the results are robust for wide range of physical parameters. For the sake
of completeness, uncorrelated disorder is also considered. Our analysis may provide a new insight in analyzing transport behavior
in different disordered lattices in presence of additional restrictions in hopping integrals.
