In certain configurations, a radio frequency system includes a level shifter operable to provide level shifting to an input signal. The level shifter is biased by a bias voltage and powered by a supply voltage and a charge pump voltage. The radio frequency system further includes a charge pump configured to provide the charge pump voltage and to receive a mode signal operable to enable the charge pump in a first state and to disable the charge pump in a second state. The radio frequency system further includes a level shifter control circuit configured to control the bias voltage to track the charge pump voltage when the mode signal is in the first state, and to control the bias voltage with the supply voltage when the mode signal is in the second state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and methods for level shifting in a radio frequency system","description":"Apparatus and methods for level shifting in a radio frequency system are provided.
