Distributed Amplifiers with Built-In Filtering for UWB Impulse Radio
Brief Description:This technology provides a distributed amplifier (DA) with built-in, on-chip filters so that the frequency response of the distributed amplifier is controlled, on chip, not only within the pass band, but also in the transition and stop bands. The very precise filtering is particularly useful for UWB impulse radios, which need t...
