OSCILLATOR, TRANSMISSION/RECEPTION DEVICE FOR A BUS SYSTEM AND METHOD FOR GENERATING A CLOCK FREQUENCY USING THE OSCILLATOR

摘要

What is disclosed is: an oscillator (150), a transmission/reception device (12) for a bus system (1) and a method for generating a clock frequency using the oscillator (150). The oscillator (150) is used for generating a clock frequency (f) and comprises a timing element (151), which has a frequency-determining capacitance (1513) for determining the frequency of the clock frequency (f) and a comparator (1514), wherein the comparator (1514) is configured to identify a threshold value voltage (UTH) up to which the frequency-determining capacitance (1513) is to be charged, and wherein the comparator (1514) has a switchable capacitance (15147) for offset compensation.
