Analog Signal Processing with Integrated Current Feedback Amplifiers
Ben Ayad, Ibrahim R. H. ; Mikula, Vladimír (oponent) ; Šimčák, Marek (oponent) ; Musil, Vladislav (vedoucí práce)
This dissertation thesis deals with the design of new functional blocks usable in area of analogue signal processing. The current feedback circuits (which in a suitable configuration can operate in voltage or current mode) are used here. This allows to achieve very promising results in the systems with a very low power supply. The versatility of the circuits will find applications in many areas. The curreent-feedback amplifier is chosen as the main building block for the detailed studies on the analog signal processing circuit design and realisation through various RC configurations. The thesis deals mainly with the study, synthesis, and design aspects of deriving new immittance functions covering inductive and supercapacitive admittances, current conveyors, voltage conveyors, high quality selective filters utilizing the transimpedance, integrators and differentiators, non-minimum phase allpass equalizers, and voltage controlled oscillators. The work deals in detail with these new particular blocks which are described theoretically and evaluated by simulations.
