A method includes identifying a first output terminal of a radio frequency front end (RFFE) switch including a single pole input terminal and a number (N) of output terminals, the first output terminal selectively connected to a single RF band path. Each of the N output terminals is a component of a respective one of N throws of the RFFE switch, with N being greater than one. The N output terminals include the first output terminal corresponding to a first throw of the N throws and at least one additional output terminal not connected to any radio frequency (RF) band path. The at least one additional output terminal includes a second output terminal corresponding to a second throw of the N throws. The method includes forming a parallel connection between the single pole input terminal and the single RF band path. The parallel connection provides at least two parallel branches for routing RF signals being transceived between the single pole input terminal and the single RF band path.

A driving device includes an electric motor, a rotating shaft, a motor housing, a printed circuit board, an electric power converting circuit, a rear frame end working as a heat radiating member, gel working as a heat transfer member, multiple mounted parts and so on. The heat radiating member is located on a side of the printed circuit board and facing a motor-side surface of the printed circuit board, to which multiple switching elements are mounted. The gel is plastically deformed and adhered to the switching elements and the heat radiating member for transferring heat of the switching elements to the heat radiating member. At least one of the mounted parts is mounted to the printed circuit board and located at a position between a through-hole opposing area and one of the switching elements, which is located at a position closest to a rotational angle sensor mounted to the printed circuit board in the through-hole opposing area.

An integrated circuit chip includes a core circuit, a first bond pad, a first switch circuit, a second configuration resistor, a control circuit, and a storage unit. The first bonding pad is coupled to a first external reference voltage through a first node, and the first node is coupled to the first external reference voltage through a bonding wire or a first configuration resistor. The first switch circuit is coupled between a first internal reference voltage and the first node. The second configuration resistor is coupled between the first internal reference voltage and the first switch circuit or between the first switch circuit and the first node. In a first mode, the control circuit turns on the first switch circuit, and writes a configuration state of the first bonding pad to the storage unit. In a second mode, the control circuit turns off the first switch circuit.

A system and method to automatically determine power plane shape in a printed circuit board (PCB) involve obtaining inputs. The inputs include a size and shape of the PCB, a set of sources, and a set of sinks associated with a power plane. The method also includes determining a center of charge (CoC) as a center of largest current density for the set of sources and the set of sinks, and creating a sub-shape corresponding with a path from each source of the set of sources and from each sink of the set of sinks to the CoC. The creating the sub-shape includes determining a width of a conductor in the path corresponding with each of the sub-shapes. The sub-shapes created for the set of sources and the set of sinks are combined as the power plane shape.

A technique for tuning a ladder-shaped inductor that achieves a finer tuning resolution by severing one or more shorts, skipping the severing of one or more shorts, and severing one or more subsequent shorts within the ladder-shaped inductor. This technique can be applied to a voltage-controlled oscillator using a differential or single-ended ladder-shaped inductor as part of the resonant circuit. Within an oscillator, such a technique provides for a more precise modulation of the effective inductance of the ladder-shaped inductor, which enables an improved tuning resolution of the operating frequency of the oscillator.

A driver IC (100) includes a pair of output terminals in each of a plurality of channels and in each of the channels, power is supplied from the pair of output terminals (OUT1 and OUT2, OUT3 and OUT4, OUT5 and OUT6 or OUT7 and OUT8) to a load (M1, M2, M3 or M4). In each of the channels, the pair of output terminals are adjacent to each other.

A microcapsule includes a shell including a conducting component, and a thermally expandable component contained in the shell and having a property of expanding by heating.

An example method includes linking a transmit line and receive line to a respective via, and printing two paths to each via, wherein each path is interrupted by two pairs of contacts. When a first resistor is in a first pair of contacts at a receive via, first signal is formed between a receive point of a first connector and the receive line. When a first capacitor is in first pair of contacts at a transmit via, second signal is formed between transmit point of first connector and the transmit line. When a second resistor is in second pair of contacts at receive via, third signal is formed between receive point of a second connector and the receive line. When a second capacitor is in second pair of contacts at transmit via, fourth signal is formed between a transmit point of second connector and the transmit line.
