Abstract
Techniques for reliable clock speed change and associated circuits and methods are disclosed. Internal voltage supplies of semiconductor devices may include oscillators and charge pump circuits. The oscillator may include at least two clock paths for generating clock signals having different clock frequencies, which can be provided to the charge pump circuit. Further, the oscillator may generate a reset signal configured to activate one clock path over the other (e.g., changing clock speeds). In some embodiments, the oscillator includes a flip-flop to align the reset signal with respect to an edge of an input clock signal supplied to the oscillator such that unintentional (undesired, unexpected) features in the output signal of the oscillator can be avoided when the oscillator changes clock speeds.
