Original Title:
Σχεδίαση ενεργού CMOS μίκτη σε τεχνολογία 65nm
Translated title:
Design of an active CMOS mixer in 65nm technology
Summary:
Thesis' objective is the design of a down-conversion active (type: Gilbert Cell) CMOS mixer.
The theoritical part of this thesis includes the explanation of the fundamental function of a mixer, the description of various mixer categories with their advantages and their disadvantages and finally, the parameters used for the assessment of any mixer.
As regards the implementation part of the thesis, it consists of an initial circuit used as basis, some modifications applied on the initial circuit for optimization purposes and finally, the simulation of the circuit using Advanced Design System 2009 of Agilent Technologies.
The frequency of the RF input signal is 2.5 GHz, the frequency of the local oscillator input signal is 2.4 GHz and the frequency of the IF output signal is 0.1 GHz. The conversion gain of the mixer is 5.85 dB, the single sideband noise figure is 7.02 dB, the input power level at 1 dB compression point is -12 dbm and the input power level at intersection point third order is -1 dbm.
