Each impedance cell includes parallel branches. Each branch includes switching units and resistors. The resistors in a branch are connected in series and contribute to an overall impedance of their corresponding impedance cell. Each switching unit is configurable to selectively bypass a corresponding one of the resistors, thereby calibrating the impedance cell. The output impedance can be set by identifying a combination of calibrated impedance cells that need to be activated in order to produce the target output impedance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tunable impedance circuit for a transmitter output stage","description":"A system, a method and circuit arrangements for adjusting an output impedance of an electric circuit involve impedance cells connected to an output terminal in parallel with one another.
