Latest Patents

Sinnesbichler holds a patent for a "Circuit configuration for controlling the operating point of a power amplifier." This invention describes a circuit configuration designed to actuate a power amplifier transistor, ensuring minimal power consumption while allowing for variable output power. The circuit is particularly suitable for amplifiers used in mobile telephones. It features a configuration that controls at least two different operating points for varying output power ranges. At the first operating point, the quiescent current in the power amplifier transistor is managed by a first balanced circuit with a temperature-compensating active feedback circuit. The second operating point utilizes a second balanced circuit with its own feedback mechanism. Additionally, a third operating range operates in saturation mode, maximizing power efficiency at peak output power, albeit with a gain that is only partially linear.
