Abstract: A modulation device may include a variable burst regulator and a current-driven clock generator. The modulation device may include a first output terminal configured to provide a modulated voltage for an operating frequency over a modulation period. The current-driven clock generator may include a second input terminal configured to receive a buffered version of the modulated voltage. The current-driven clock generator may include a second output terminal configured to provide a modulated current during the modulation period. The operating frequency may be proportional to the modulated current. The operating frequency may control the operating frequency over the modulation period.
