This paper describes a 24 GHz quadrature demodulator (IQ-demodulator) using 65 nm bulk CMOS technology. The proposed IQ-demodulator consists of two direct down conversion mixers and a polyphase filter for 90° phase shifting. The two mixers are matched to 50 ohm by an on-chip bias-tee matching network with ESD protection. The parasitic inductance… CONTINUE READING
