Abstract
This thesis introduces a component of the Radio Frequency transceiver called the mixer. The
mixer is a critical component in the RF systems, as a result of its ability for frequency
conversion. This passages focuses on the design analysis and simulation of active down-conversion mixer. This mixer is described by its important design properties which consist of
conversion gain, linearity, noise figure, and port isolation. The topologies that are given in this
passage range from the most commonly known mixer design, to implement the design methods
that are utilized to build the mixer important design properties as the request of CMOS
technology and the overall RF system rises. All mixer topologies were designed and simulated
using TSMC 0.18 μm CMOS technology in Advanced Design Systems, a test system utilized
particularly for RF designs. The design was able to produce the conversion gain about 12.86 dB
and 12.85 dB at 401 MHz – 406 MHz respectively. The NF obtained in this topology was 11.2
dB at 401.7 MHz and started to go below 11.19 dB at 405.8 MHz. IP1db and IIP3 was also able
to meet the design target specification. Finally, the power consumption is 6.17 Mw at a 1.8 V.
