Coherent demodulation of a received signal requires the same carrier signal as the one used by the transmitter (TX). Thus, the RX needs to reconstruct the carrier from the received carrier-less signal ...

This work describes a 65 nm SOI CMOS passive mixer architecture consisting of a n-MOS cold-FET and coplanar waveguide (CPW) transmission line matching networks for six-port IQ demodulation of ...
