  • Patent number: 9954487
    Abstract: A method for controlling a semiconductor circuit, including forming an inductor and a capacitor on a substrate, which are inductively coupled to one another. The inductor has an inductance value while the capacitor has a capacitance value. The inductor and capacitor make up an oscillator circuit with two terminals. Eddy currents are generated through the capacitor when an operating current flows along the inductor. These eddy currents influence, by inductive coupling, the inductance value and performance of the oscillator circuit, thus simultaneously tuning the inductance and capacitance of the oscillator circuit.

  • Patent number: 9559162
    Abstract: A first pair of resistors formed in a first layer of material, and a second pair of resistors formed in the first layer or in a second layer can be wired into a Wheatstone bridge to form a temperature sensor. Either layer can include a semiconductor or a dielectric. In a semiconductor layer, a pair of resistors can be doped areas of the layer, while in a dielectric, a pair of resistors can be material deposited in cavities in the layer, such as material from an added “middle-of-line” (MOL) metallization layer.
