    摘要: Disclosed are a circuit and method for amplifying the power of a multi-tone input signal. The multi-tone input signal is filtered separating out one signal having a tone at a fundamental frequency from another signal having additional tones at additional frequencies. The signal having the tone at the fundamental frequency is amplified and then filtered removing any harmonics added during amplification. The signals are then recombined generating a multi-tone output signal, wherein the tone at the fundamental frequency is boosted (i.e., has a higher power in the multi-tone output signal than in the multi-tone input signal), but the additional tones at the additional frequencies are not (i.e., the additional tones at the additional frequencies have essentially the same power in the multi-tone output and input signals). Also disclosed herein are embodiments of a testing system and method incorporating the above-described circuit to allow for testing of high power devices.

    摘要: Disclosed is semiconductor structure with an insulator layer on a semiconductor substrate and a device layer is on the insulator layer. The substrate is doped with a relatively low dose of a dopant having a given conductivity type such that it has a relatively high resistivity. Additionally, a portion of the semiconductor substrate immediately adjacent to the insulator layer can be doped with a slightly higher dose of the same dopant, a different dopant having the same conductivity type or a combination thereof. Optionally, micro-cavities are created within this same portion so as to balance out any increase in conductivity with a corresponding increase in resistivity. Increasing the dopant concentration at the semiconductor substrate-insulator layer interface raises the threshold voltage (Vt) of any resulting parasitic capacitors and, thereby reduces harmonic behavior. Also disclosed herein are embodiments of a method and a design structure for such a semiconductor structure.
