Abstract—We report an ultra-low-voltage RF receiver for
applications in the 2.4 GHz band, designed in a 90 nm CMOS
technology. The sliding-IF receiver prototype includes an LNA, an
image-reject LC filter with single-ended to differential conversion,
an RF mixer , an LC IF filter, a quadrature IF mixer , RF and
IF LO buffers, and an I/Q baseband section with a VGA and a
low-pass channel-select filter in each path, all integrated on-chip.
