摘要： Systems and methods provide analog delay elements, which may be utilized in isolation or in a cascade. For example, a delay element may include a broadband amplifier and a passive, programmable filter, which may provide a desired magnitude and group delay response over a wide frequency range while being tolerant of process variations.

摘要： An inductor for an integrated circuit made of a plurality of stacked, electrically coupled, metal layers. Each metal layer includes an inductor formed of a spiral pattern, which except for the top and bottom inductors, are electrically coupled to the spiral inductor formed on the metal layer above and below with an electrical path or via formed between each metal layer. The top and bottom inductors are electrically coupled to the inductor directly below and above, respectively.

摘要： A low-voltage constrained coefficient adaptation and multiplication is provided. To provide the constrained coefficient adaptation, an adder adds an adaptive differential control voltage to a forcing differential control voltage to provide an effective coefficient. The adder is configured such that the forcing differential control voltage can prevent the adaptive differential control voltage from producing a sign change in the effective coefficient.
