Modular approach to desing of modern analog devices in CMOS technology

The presented dissertation thesis deals with modular design of analog circuits in CMOS technology. The goal of the work is to design a set of modular microelectronic building blocks and realize the selected modern active circuits, working primarily in current mode. Nevertheless, the modular approach can be used for design of generally known classical elements, e.g. opamps, as well. As a part of the work, the development of the totally new highly versatile active circuit CCTA has been done, including detailed analysis of utilization and introduction of the most interesting applications. This circuit CCTA, together with relative, already theoretically treated circuit CDTA, has been realized here for the first time, in two different topologies. Final circuits were tested. On the basis of measurement results the library of behavioral models for PSpice was created, including exemplary simulations of the selected applications. Based on the obtained knowledge the brief comparison of voltage mode circuits and current mode circuits was done
