A device includes a port and a transformer. The transformer includes a first coil that has a first node and a second node and a second coil that is coupled to the output port. The device also includes a pulse generator coupled to the first node to generate two or more pulses with a first period on the first node and a delay module that is coupled between the second node of the first coil and the pulse generator. The delay module is generates a time delay to the two or more pulses of the pulse generator before the two or more pulses are delivered to the second node. The second coil provides a signal at the port.

Cancellation technique for second harmonic distortion and spectral image in DACS and digital transmitters

An system includes a port to receive a number of bits at a first frequency. One or more cells generate a signal for a channel with a channel frequency that is N times greater than the first frequency. The cells transmit at a second frequency that is M times greater than the first frequency but is smaller than the channel frequency. Interface links are coupled between a portion of the input bits of the port and the one or more cells and the portion of the input bits is encoded by thermometer coded T bits such that each one of the T bits is encoded by M repeated parallel bits having a value of a respective T bit. Each interface link includes M interface lines between each T bit and each first cell, and M is smaller than N to reduce the number of interface lines for the T bits.

Hybrid rate interface to reduce power consumption and area in high-speed DACs and digital transmitters

A transmitter includes a first digital-to-analog converter (DAC) circuit consisting of a first set of unary cells to mix a first set of digital input data with a first clock signal. A second DAC circuit includes a second set of unary cells to mix a second set of digital input data with a second clock signal. A third circuit provides signals to the first DAC circuit and the second DAC circuit to implement an assignment scheme to assign either an in-phase (I) component or a quadrature (Q) component to the first set of unary cells and the second set of unary cells. Based on the assignment scheme, the first set of digital input data include I-data and Q-data, and the second set of digital input data include I-data and Q-data.

Dynamic assignment with phase-preserving clipping technique for digital transmitters and power amplifiers

A first electronic device may enable generation, updating, and/or storage of user configuration information. The user configuration information may comprise information pertaining to device configuration and/or operational preferences specific to the device user and/or various use settings, connectivity, and/or use of available resources. The generation, updating, and/or storage of the user configuration information may be performed manually and/or automatically, and may be performed directly within the first electronic device and/or via networked devices, which may communicatively coupled to the first electronic device. A second electronic device may be enabled to be communicatively coupled to the first electronic device and/or the networked devices. The second electronic device may then be enabled to download existing user configuration information from the first electronic device and/or the networked device, and the downloaded user configuration may be utilized to configure the second electronic device.

Method and system for a networked self-configuring communication device utilizing user preference information

A wireless communication device includes an antenna to receive a signal, a low noise amplifier, and circuitry that determines the power level of the signal. The circuitry also determines whether the signal includes a packet, and causes the low noise amplifier to amplify the signal when the signal includes a packet and the power level of the signal is below a threshold. The circuitry also causes the low noise amplifier to be bypassed when the signal does not include a packet, or the power level of the signal is above the predetermined threshold and the signal includes a packet.

Low gain listen

A linear, low noise, high quality factor (Q) and widely tunable notch filter circuit includes one or more first reactive elements coupled between a first filter node and a first node. The notch filter circuit further includes a multi-branch circuit having multiple parallel branches and coupled between the first node and a second node. Each branch of the multi-branch circuit includes at least a switch coupled to a variable capacitor. A notch frequency of the notch filter circuit is tunable by adjusting a capacitance of the variable capacitor.

A wireless communication device includes a first circuit including a baseband circuit and a radio circuit, and at least one frontend module (FEM) remote from the first circuit and placed in close proximity to and coupled to at least one radio-frequency (RF) antenna. The FEM is coupled to the first circuit via interface circuitry. An FEM comprises a frontend (FE) circuit including one or more low-noise amplifiers (LNAs), one or more power amplifiers (PAs), and at least one of a multi-pole switch and a multiplexer. The multi-pole switch and the multiplexer being implemented on a first side of the FEM coupled to the interface circuitry. The interface circuitry includes at least some of filters, splitters, multi-pole switches, and multiplexers to reduce a count of interconnect routes to the at least one FEM.

Wireless transceiver with remote frontend

Systems and method provided herein relate to reducing distortion of signals introduced by components on a phase path of a radio frequency system polar architecture. To reduce phase path distortion, a pre-distortion is introduced prior to a distortion caused by the components on the phase path. The pre-distortion in conjunction with the component distortion results in a transmission signal that forms its expected shape.

Disclosed herein are systems, apparatuses, and methods for locating wireless-enabled components, and applications thereof. Such an apparatus includes a wireless-enabled component (WEC), which may be a functional block of an integrated circuit (IC), an IC, or a device that includes an IC. The WEC includes a functional module (e.g., a processing resource or a memory resource) and an antenna element coupled to the functional module. The antenna element is configured to (i) transmit a search signal to locate a proximally situated WEC and (ii) transmit a communication signal to communicate with the proximally situated WEC. The antenna element may be a phased array, an electrically steered phased array, a mechanically steered phased array, a directional antenna, a mechanically steered directional antenna, an RF antenna, an optical antenna, and/or any combination thereof.
