ARC oscillator with blocks with variable parameter
Bořecký, Tomáš ; Kolka, Zdeněk (referee) ; Slezák, Josef (advisor)
Within the master’s thesis there is comparison of different structures of ARC oscillators with respect to their harmonic distortion. Individual blocks of oscillator are analyzed. Attention is paid to choosing and design of suitable ARC filter structure and possibilities of its tuning. Also possibilities of stabilization of amplitude are analyzed. Different types of controlled amplifiers and circuits for controlling of their amplification are discussed. Next captures are focused to designing and simulation of the ARC oscillator. The oscillator can be tuned in the frequency range from 100 Hz to 20 kHz with harmonic distortion smaller than 1%. At the end of the thesis, practical realization of the proposed circuit is described. Also results of the measurement of parameters of the oscillator are given.
