Abstract: A power converter can include an electrical isolation circuit between input and output nodes. An input signal monitor node can be provided, such as on a converter output side of the isolation circuit. In an example, a peak detection circuit can be coupled to the input signal monitor node. The output node of the power converter can be configured to supply an output power signal that is a function of an input signal at the input node. The power converter can include multiple, independently-switchable switches at one or more of the input and output sides of the isolation circuit. In an example, the power converter with the input signal monitor node can be configured as a bias supply to provide power, at the output node, to a controller circuit for a main stage power converter circuit.

Abstract: In one example implementation, the present disclosure provides a loop filter for use in a continuous-time sigma-delta analog-to-digital converter. Specifically, a capacitive feedback digital-to-analog converter path is provided at the input of a first opamp in a series of opamp integrators. The capacitive feedback digital-to-analog converter at the input of the first opamp reduces the signal content at the output of the first opamp, and thereby reduces the output swing of the first opamp. A reduction in output swing provides a more efficient loop filter.

Abstract: Various digital pre-distortion systems for use in transmitters are disclosed. The digital pre-distortion system comprises an observing path, which performs either undersampling or radio frequency sampling of the output of a power amplifier. Undersampling may be performed at a rate, which causes aliasing to occur in the undersampled frequency domain. Both undersampling and radio frequency sampling reduces the complexity of the digital pre-distortion system by removing any down mixing modules or anti-aliasing modules, while maintaining reasonable performance of the digital pre-distortion systems.

Abstract: Apparatus and methods for current sensing in switching regulators are disclosed. In certain implementations, a current sensing circuit senses current of a power stage of a power converter. The power converter can include first and second transistors. The current sensing circuit comprises a transistor that is a scaled version of one of the transistors of the power converter. A circuit of the current sensing circuit matches a drain-to-source voltage of the transistor of the current sensing circuit to the corresponding transistor of the power converter. A current mirror generates a current that mirrors the current flowing through the transistor of the current sensing circuit. A first resistor converts the mirrored current to a current sensed signal.

Abstract: A method can reuse at least one pin in demultiplexing (demuxing) a voltage from a pin. The method can be used to set an accurate current limit threshold in a design for test (DFT) phase and, thus, to accurately set a trimming code of a current limiter. The method uses the property that a power MOSFET has almost a same conductive resistance at a large drain current. Thus, the current limit threshold can be set according to an accurate drain-to-source voltage Vds at a small current sink that is less than a maximum current that ATE is able to provide. An accurate voltage Vds can be measured through Kelvin sensing drain and source pins of the power MOSFET, which are connected to a current sense circuit.
