BANDWIDTH IMPROVEMENT FOR AMPLIFIERS

摘要

A circuit may include an amplifying circuit and a t-coil inductor. The amplifying circuit may include an input node, an output node, an amplifier, and a feedback loop. The feedback loop may be coupled between the input node and the output node. The amplifying circuit may be configured to receive a current signal on the input node and to output a voltage signal based on the current signal on the output node. The t-coil inductor may include a first portion and a second portion. A first node of the first portion may be coupled to the input node of the amplifying circuit and the second portion may be included in the feedback loop.
