摘要： A system and method for digitally providing impedance mismatch compensation for a communications medium in a communications device. A method comprises producing a power amplifier (PA) output signal, providing the PA output signal to a digitally-controlled transmission line (DCTL), transforming a first load impedance to a second load impedance producing a DCTL output, and coupling the DCTL output to an antenna. The PA having the first load impedance and the transforming is controlled by a digital control word provided to the DCTL.

摘要： There are numerous types of dividers that have been employed at various frequency ranges. For many very high frequency ranges (i.e., above 30 GHz), dividers in CMOS have been developed. However, many of these designs use multiple stages. Here, however, a single stage divider has been provided that is adapted to operate at very high frequencies (i.e., 120 GHz). To accomplish this, it uses parasitic capacitances in conjunction with inductor(s) to form an LC tanks so as to take advantages of parasitics that normal degrade performance.
摘要翻译：在各种频率范围内使用了多种类型的分频器。对于许多非常高的频率范围（即，高于30GHz），已经开发了CMOS中的分频器。然而，许多这些设计使用多个阶段。然而，这里提供了适用于在非常高的频率（即120GHz）下工作的单级分频器。为了实现这一点，它使用寄生电容与电感器一起形成LC箱，以便利用正常退化性能的寄生效应。
