Abstract
In various embodiments, an electronic component is provided. The electronic component may include a supply bus configured to provide a supply voltage for an electronic circuit. The electronic component may further include a voltage-controlled oscillator, which is coupled to the supply bus and is configured to generate a clock signal with a clock frequency according to the supply voltage. The electronic component may further include at least one reference oscillator, which is configured to generate a reference clock signal with a reference clock frequency, and a comparator, which is coupled to the voltage-controlled oscillator and the at least one reference oscillator and is configured to compare the clock signal with the reference clock signal and, on the basis of the comparison, either to output the clock signal to the electronic circuit or to suppress it.
