Design of current sense comparators for automotive front lighting
Schilhab, Jan ; Prokop, Roman (referee) ; Kledrowetz, Vilém (advisor)
The diploma thesis deals with the problem of current sensing on integrated DC-DC converter switches using a comparator with reference current. Various current sensing methods are discussed in the thesis and a method of sensing current on a MOS switch using a smaller channel width reference transistor is thoroughly described. The paper also describes the basic properties of comparators and a suitable methodology for designing a fast comparator operating continuously in time. A major part of the thesis is devoted to the design of comparator blocks for current sensing at the top and bottom switches on the transistor level and presentation of the results obtained by simulations in Cadence Virtuoso environment. At the end, simulations are presented to verify the function of the designed blocks in a simplified buck DC-DC converter system.
Configuring Integrated Circuit with a Single External Resistor
Chmelař, Martin ; Šteffan, Pavel (referee) ; Boušek, Jaroslav (advisor)
This thesis deals with the design and simulation of an analog circuit that is able to adjust the functions of other parts of the circuit by connecting an external resistor. The design is done in submicron technology.
