A USB-C to MoCA converter includes a USB-C interface for receiving and transmitting USB-C power and data, a MoCA interface handling the reception and transmission of USB-C power and data. A MoCA data / power handling converter is configurated to manage MoCA power and data in both directions. A USB / MoCA data converter is coupled between USB-C interface and MoCA interface to determine the communication protocol and to process incoming USB-C data signals into MoCA data formats and vice versa. A power converter is coupled between USB-C interface and MoCA interface to convert USB-C voltage of the USB-C power to fit MoCA voltage. A USB-C power delivery controller is connected between USB-C interface and the power converter to power a device connected to MoCA interface. The USB-C to MoCA converter enables data and power exchange between USB-C and MoCA interfaces for promoting compatibility and smooth operation.

In an example, the transceiver includes a first-stage downconverter configured to convert a radio frequency (RF) input analog signal to a first intermediate frequency (IF1) narrowband (NB) input analog signal; a second-stage downconverter configured to convert the IF1 NB input analog signal or a millimeter wave (mmW) input analog signal to a second intermediate frequency (IF2) NB input analog signal; one or more analog to digital converters (ADCs) configured to convert one or more of the IF1 NB input analog signal, the IF2 NB input analog signal, and the RF input analog signal to digital input signals; and a processor configured to control the first-stage downconverter to set a center frequency and bandwidth of the IF1 NB input analog signal and control the second-stage downconverter to set a center frequency and bandwidth of the IF2 NB input analog signal.

The invention discloses an apparatus and method for non-linearity cancellation in an electronic system. In some embodiments, an electronic system includes two or more circuit channels that process a common input signal in parallel, each circuit channel including at least one instance of a non-linear behavior circuit. Thus, a non-linear circuit is replicated and included in each circuit channel at least once. Each circuit channel has an input scaling factor and an output scaling factor that can be changed from one circuit channel to another. The scaled output signals of the circuit channels are combined to generate a combined output signal. The input and output scaling factors are selected to eliminate or reduce nonlinearity.

Systems and methods for operating a signal converter. The methods comprise; establishing a first interface between the signal converter and an analog device of a first network, and a second interface between the signal converter and an edge node of a different second network; supplying power to a first circuit portion of the signal converter from the analog device, and power to a second circuit portion of the signal converter from the edge node; receiving, by the first circuit portion, a first analog signal from the analog device; converting, by the first circuit portion, the first analog signal to a first electrical signal; formatting, by the second circuit portion, the first electrical signal for communication over the second network; and communicating, from the second circuit portion, the formatted first electrical signal to the edge node.

The present invention relates generally to the field of microphones, and more particularly to a microphone including an analog port and a digital port through which audio may be output. The microphone may be configured to obtain power from a host device and may include circuitry for selectively routing audio signals to the one or more ports. Advantageously, the microphone may be configured to connect with a variety of host devices and may facilitate functioning as a USB microphone via the digital port, while the analog port may be used as a headphone output

Apparatus and methods for nonlinearity cancellation in electronic systems are disclosed. In certain embodiments, an electronic system includes two or more circuit channels that process a common input signal in parallel and that each include at least one instantiation of a circuit that behaves nonlinearly. Thus, the nonlinear circuit is replicated and included at least once in each circuit channel. Each of the circuit channels has an input scaling factor and an output scaling factor that can vary from one circuit channel to another. The output signals from the circuit channels after scaling are combined to generate a combined output signal. The input and output scaling factors are selected to cancel or reduce nonlinearities.

At the input end of the AMAC, each DAC corresponds to multiple input ports, which are shared in a time-division multiplexing manner through the first M1-MUX module and the first 1M-MUX module; at the output end of the AMAC, each ADC corresponds to multiple output ports, which are shared in a time-division multiplexing manner through the second M1-MUX module and the second 1M-MUX module; the number of DACs and ADCs is reduced, and the chip area is reduced.
