U radu je prikazan simulacioni model nove metode za generisanje naponskog šuma uniformne raspodele vrednosti. Ovaj šum, diter, je ključni element u radu stohastičke analogno digitalne (AD) konverzije. Za razliku od uobičajenog načina generisanja primenom šift registra sa linearnom povratnom spregom (Linear Feedback Shift Register - LFSR) i digitalno analognog (DA)konvertora nova metoda je zasnovana na asinhronom odabiranju testerastog ili trougaonog napona. Kao osnovni dobitak predložene metode se navodi kontinualnost ditera po vrednosti, za razliku od prethodnog rešenja koje karakteriše diskretan diter. Primena kontinualnog ditera omogućava dalje povećanje efektivne rezolucije stohastičkog AD konvertora.
