Originální abstrakt

This contribution deals with simple and adjustable triangular and square wave generator employing diamond transistor, two voltage controllable amplifiers, one resistor and grounded capacitor. Main aim is the exploration of adjustable features of a real circuit compared to ideal estimations. Detailed analysis and experimental tests proved that nearly ideal estimations give inaccurate results. We performed refinements corrections where existence of saturation in voltage controllable amplifier, that tunes frequency, was considered in calculations. Results proved possible controllability in discussed solution but reveal also high dependence of features (repeating frequency and produced amplitudes) on features of particular active element (mainly voltage controllable amplifier) in the design because each active element has little bit different output saturation levels (dependent on fabrication tolerance, etc.).
