Abstract
This article presents the theory and implementation
of a quadrature and differential RF front-end receiver. Com-
bining balun, low-noise amplifier (LNA), mixer, and oscillator
in a single stage, the proposed circuit, named the Blixator,
is well suited for low-power applications. The baseband’s tran-
simpedance amplifier (TIA) also shares part of its dc current
with the Blixator cell, resulting in sub-milliwatt power consump-
tion. To avoid additional power and area by quadrature LO
generation, the
