In certain configurations, a method of negative voltage generation in a wireless device is provided. The method includes generating a regulated voltage from a battery voltage using a voltage regulator, powering a first charge pump and a second charge pump using the regulated voltage, generating a first negative voltage based on timing of a first clock phase using the first charge pump, generating a second negative voltage based on the first negative voltage and on timing of a second clock phase using the second charge pump, and generating the first clock phase and the second clock phase with different phases using a poly-phase oscillator such that the first charge pump and the second charge pump draw from the regulated voltage at different points in time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and methods for negative voltage generation with reduced clock feed-through","description":"Apparatus and methods for negative voltage generation with reduced clock feed-through are provided.
