摘要： A resonator comprising a beam formed from a first material having a first Young's modulus and a first temperature coefficient of the first Young's modulus, and a second material having a second Young's modulus and a second temperature coefficient of the second Young's modulus, a sign of the second temperature coefficient being opposite to a sign of the first temperature coefficient at least within operating conditions of the resonator, wherein the ratio of the cross sectional area of the first material to the cross sectional area of the second material varies along the length of the beam, the cross sectional areas being measured substantially perpendicularly to the beam.

摘要： A resonator having an effective spring constant (kz) and comprising a beam having a beam spring constant (kB) adapted to resonate in an oscillation direction, and extending at a non-zero angle (θ) to the oscillation direction, wherein the resonator has a predetermined geometry and is formed from one or more materials, the or each material having a coefficient of thermal expansion (CTE), the CTE of the or each material together with the predetermined geometry of the resonator causing θ to vary with temperature, such that the temperature dependence of the beam spring constant is compensated for, resulting in the effective spring constant of the resonator remaining substantially constant within an operating temperature range.

摘要： A method and circuit in which the drive strength of a FinFET transistor can be selectively modified, and in particular can be selectively reduced, by omitting the LDD extension formation in the source and/or in the drain of the FinFET.One application of this approach is to enable differentiation of the drive strengths of transistors in an integrated circuit by applying the technique to some, but not all, of the transistors in the integrated circuit. In particular in a SRAM cell formed from FinFET transistors the application of the technique to the pass-gate transistors, which leads to a reduction of the drive strength of the pass-gate transistors relative to the drive strength of the pull-up and pull-down transistors, results in improved SRAM cell performance.
