Abstract

U poglavlju 2. ovog rada opisan je i dokumentiran postupak projektiranja naponski
kontroliranog oscilatora s negativnim otporom u 180 nm tehnologiji tranzistora s
horizontalnim tokom struje. Opisana je fizikalna slika rada oscilatora s negativnim otporom.
Navedene su glavne karakteristike VCO-a te opisan utjecaj parametara titrajnog kruga i
tranzistora. VCO je projektiran u dvije različite izvedbe obzirom na izvedbu titrajnog kruga
te dvije izvedbe s različitim brojem HCBT-a u diferencijalnom paru s titrajnim krugom na
čipu. Oscilator je simuliran pomoću programskog alata “ADS”, a layout je izrađen pomoću
programskog alata “Cadence”.
U poglavlju 3. dokumentirana je analiza mixera projektiranog u 180 nm tehnologiji
tranzistora s horizontalnim tokom struje. Analiza je provedena u dva dijela – simulacijski
pomoću programskog alata “ADS” i fizički na čipu pomoću laboratorijske mjerne opreme i
programskog alata “Labview”. U simulacijskom dijelu ispitan je i objašnjen utjecaj
parametara HCBT-a Re i Nk na linearnost (IIP3) i pojačanje (CG) mixera. U mjerenjima na
čipu ispitan je utjecaj statičkih radnih točaka HCBT-a na IIP3 i CG mixera.

Abstract (english)

In Chapter 2. of this work designing a VCO with a negative resistance in 180 nm
transistor technology with horizontal flow of current is described and documented.
Oscillator with negative resistance working operation is described. Main characteristics of
the VCO's are listed and influence of a resonant circuit’s parameters are described. VCO is
designed in two different versions depending of location of the resonant circuit, and two
versions with different numbers of HCBT’s in a differential pair with a resonant circuit on a
chip. The oscillator is simulated using the software tool "ADS" and the layout was designed
using the software tool "Cadence".
In Chapter 3 analysis of mixer designed in 180 nm transistor technology with horizontal
flow of current is documented. There was two separated parts of analysis – a simulation part
using the software tool "ADS" and on-chip laboratory measurement using laboratory
equipment and software tool "Labview". In the simulation section influence of HCBT
parameters Re and Nk on linearity (IIP3) and conversiongain (CG) was examined and
explained. In the on–chip measurements influence of static working point of HCBT’s on
IIP3 and CG of mixer are examined and explained.
