The current source includes an n-type field effect transistor that is biased to operate as a constant current source. The current source is configured to provide the output current to the capacitor and charge the capacitor during a first time period associated with operation of a load. The current source is also configured to provide the output current to the load and the capacitor is configured to provide an additional current to the load during a second time period associated with operation of the load. The load could represent an electronic device having a time-varying output power characteristic, such as a wireless radio."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Constant input current filter for power supplies and related system and method","description":"A system includes a capacitor and a current source configured to draw a constant input current from a power source and to generate an output current.
