Originální abstrakt

This paper focuses on analysis of impact of voltage gain of comparator on features of designed triangular and sine wave generator. Newly designed generator employs minimal number of passive and active components based on the simple voltage controllable amplifier and electronically controllable current conveyor or adjustable current amplifier. The generator has simple structure with easily available electronic control of repeating frequency and duty cycle. Detailed PSpice analyses of the modified generator are provided and relevant results of experimental measurements are shown. Discussion of non-ideal effects of voltage gain (A) of controllable amplifier used as comparator on generated amplitudes, on repeating frequency and on duty cycle as well as effects of statistical dispersion of important parameters are given. Observed behavior was analyzed not only by simulations but also by experimental measurements.
