摘要： Embodiments discussed herein generally relate to utilizing non-volatile memory elements to continuously drive other circuitry. There are many advantages to utilizing non-volatile memory to continuously drive other circuitry. For example, back end of the line (BEOL) compatible process may be used to fabricate the non-volatile memory elements that does not affect any front end of the line (FEOL) devices. This allows for an earlier integration of non-volatile technology into the latest state-of-the-art semiconductor process nodes. This is specifically important for FPGA and CPLDs, which make use of the latest process nodes.

摘要： The present disclosure generally relates to the combination of MEMS intrinsic technology with specifically designed solid state ESD protection circuits in state of the art solid state technology for RF applications. Using ESD protection in MEMS devices has some level of complexity in the integration which can be seen by some as a disadvantage. However, the net benefits in the level of overall performance for insertion loss, isolation and linearity outweighs the disadvantages.

摘要： The present disclosure generally relates to a mechanism for making a MEMS switch that can switch large electrical powers. Extra landing electrodes are employed that provide added electrical contact along the MEMS device so that when in contact current and heat are removed from the MEMS structure close to the hottest points.

摘要： The present disclosure generally relates to any device capable of wireless communication, such as a mobile telephone or wearable device, having one or more antennas. The antenna has a structure with multiple resonances to cover all commercial wireless communications bands from a single antenna with one feed connection to the main radio system. The antenna is usable where there are two highly efficient, closely spaced resonances in the lower part of the frequency band. One of those resonances can be adjusted in real time by using a variable reactance attached to the radiator while the other resonance is fixed.

摘要： The present disclosure generally relates to a device having a capacitance sensor that detects a change in capacitance that occurs in the antenna whenever the antenna is in close proximity to a user's hand and/or head. Following detection of the capacitance change, the capacitance of the antenna may be changed by using a variable capacitor that is coupled to the sensor through a controller.

摘要： The present invention generally relates to a MEMS device having a plurality of cantilevers that are coupled together in an anchor region and/or by legs that are coupled in a center area of the cantilever. The legs ensure that each cantilever can move/release from above the RF electrode at the same voltage. The anchor region coupling matches the mechanical stiffness in all sections of the cantilever so that all of the cantilevers move together.

摘要： The present disclosure generally relates to a MEMS DVC utilizing one or more MIM capacitors located in the anchor of the DVC and an Ohmic contact located on the RF-electrode. The MIM capacitor in combination with the ohmic MEMS device ensures that a stable capacitance for the MEMS DVC is achieved with applied RF power.

摘要： Embodiments disclosed herein generally relate to power amplifier matching circuits used for matching impedance and harmonic control in a device, such as a cellular phone. In one example, a power amplifier matching circuit includes two DVCs, four inductors, a transistor, and a capacitor. Utilizing the two DVCs, the impedance matching ratio and the center frequency of the circuit are capable of adjustment as needed. Moreover, the inclusion of the two DVCs may also prevent harmonic frequencies from undesirably passing through the power amplifier matching circuit to the antenna of a cellular device. The power amplifier matching circuit may be used in conjunction with an amplifier, where the output of the amplifier is proportional to the current in the circuit.
