In this thesis, three low-noise active mixing circuits are presented in CMOS technology. Mixers can be found at the front-end of almost every communication systems. However, despite many advantages the active mixers have, ...

This thesis focuses on the design of radio-frequency (RF) mixers, including a broadband downconverter mixer, an upconverter mixer and a downconverter mixer with high linearity. The basic mixer topology used in this thesis ...

This thesis examines the design of a QPSK demodulator frontend for GPON transceiver at end user's side. Since lowering the cost of the terminal transceivers in an access network like GPON is a key requirement, CMOS technology ...
