Abstract: An electronic device includes: a switching regulator configured to generate a conversion voltage with respect to an input voltage, based on a switching signal of a first frequency, and output the conversion voltage; a stabilization circuit including a capacitor element connected to a load device via a first node and configured to generate a load voltage by stabilizing the conversion voltage by using the capacitor element and output the load voltage to the load device; a frequency sensing circuit configured to sense a frequency of the load voltage and output sensing information about the frequency of the load voltage; and a frequency booster circuit configured to form a first current path connected to the first node, based on the sensing information.

Abstract: An adhesive tape sticking apparatus includes a chamber includes a lower chamber and an upper chamber. The lower chamber includes a first inner space and the upper chamber includes a second inner space. An adhesive tape sheet is positioned between the upper chamber and the lower chamber. A substrate support is movable upward and downward within the lower chamber and is configured to support a substrate. A differential pressure generator is configured to generate a differential pressure between the first inner space and the second inner space. A tape support plate positioned between a first sidewall of the lower chamber and a circumferential edge of the substrate. The tape support plate is configured to contact at least a portion of the adhesive tape sheet when the adhesive tape sheet bends downward toward the first inner space when the differential pressure is generated between the first and second inner spaces.
