Abstract
A phased array architecture configured for current reuse is disclosed. In an exemplary embodiment, an apparatus includes a current mode phase rotator (PR) module configured to generate phase shifted in-phase (I) and quadrature-phase (Q) current signals, and a current mode residual sideband (RSB) correction module configured to correct residual sideband error associated with the phase shifted I and Q current signals. The RSB correction module and the PR module form a phased array element configured to reuse a DC supply current.
