  We show how charged levitated nano- and micro-particles can be cooled by
interfacing them with an $RLC$ circuit. All-electrical levitation and cooling
is applicable to a wide range of particle sizes and materials, and will enable
state-of-the-art force sensing within an electrically networked system.
Exploring the cooling limits in the presence of realistic noise we find that
the quantum regime of particle motion can be reached in cryogenic environments
both for passive resistive cooling and for an active feedback scheme, paving
the way to levitated quantum electromechanics.
