Bulk-driven current mirrors
Kováčik, Martin ; Prokop, Roman (referee) ; Khateb, Fabian (advisor)
My bachelor’s thesis is about bulk-driven CMOS principle for several analog circuit projects. A substrate gate is used for signal input to achieve low supply voltage and low wattage while keeping parameters adequate to current structures. The goal of my work was to design current mirror with low supply voltage and low wattage with usage of this principle. In my work there are basic data about bulk-driven technology and MOFSET transistors used in this technology. My project contains different kinds of schemes of bulk-driven current mirrors which are compared with conventional gate-driven current mirror. These circuits are simulated in Orcard Pspise program.

Analysis and realization of frequency filter tunable by active component parameter
Vrba, Adam ; Khateb, Fabian (referee) ; Prokop, Roman (advisor)
This work analyzes tuning capabilities of different fully integrated active filter topologies. Work only deals with continuous time active filters. Topologies described in this work differ in type of active element and in method of frequency tuning. Techniques of tunning are proved on second order low pass filter. Filter topologies are compared from tunning capabilities and from point of total harmonic distortion. The main building block of all filters is integrator.

Design of Differential Difference Amplifier in CMOS technology
Trojan, Vladimír ; Khateb, Fabian (referee) ; Kledrowetz, Vilém (advisor)
The bachelor's thesis deals with the design of differential difference amplifier (DDA) in technology TSMC 0,18 with maximum input and output common mode range, minimum power dissipation and area on chip. The thesis describes the basics of CMOS technology, commonly used structures of analog integrated circuits and operational amplifiers. Main focus of the thesis is design of circuit of DDA. Designing and simulations of DDA parameters were made in program Cadence Virtuoso and ADE Assembler simulation environment. Layout of DDA was designed in Layout XL environment.

Design of extremly low-voltage rectifier in CMOS technology
Musilová, Nikola ; Šteffan, Pavel (referee) ; Khateb, Fabian (advisor)
The aim of this work is to design a low-voltage and low-power rectifier using CMOS technology and an operational amplifier for input voltages in the order of tens of mV, which correspond to sensor and biomedical applications. The circuit allows both half-wave and full-wave rectification. The key parameters are high gain and very low power consumption of the operational amplifiers that make up the rectifier.

Preamplifier for biological signals processing
Derishev, Anton ; Prokop, Roman (referee) ; Khateb, Fabian (advisor)
The work deals with the design and optimization of amplifiers in CMOS technology with low supply voltage and low power consumption. The main aim is to design an amplifier to amplify the biological signal. The first part is a brief introduction to the theory of biological signals. The work also contains a brief description of the biological signal processing methods and their properties. The important part is the description of the methods to reduce the supply voltage of the amplifier. The practical part of this thesis focuses on the design amplifiers with low supply voltage and low power consumption. All active elements and application examples have been verified by PSpice simulator using the 0.18 µm TSMC CMOS parameters. Simulated plots are included in this thesis to illustrate behavior of structures.
