Abstract
Official abstract text for this publication.
Split amplifiers with configurable gain and linearization circuitry are disclosed. In an exemplary design, an apparatus includes first and second amplifier circuits and a linearization circuit, which may be part of an amplifier. The first and second amplifier circuits are coupled in parallel and to an amplifier input. The linearization circuit is also coupled to the amplifier input. The first and second amplifier circuits are enabled in a high-gain mode. One of the first and second amplifier circuits is enabled in a low-gain mode. The linearization circuit is enabled in the second mode and disabled in the first mode. The amplifier is split into multiple sections. Each section includes an amplifier circuit and is a fraction of the amplifier. High linearly may be obtained using one amplifier circuit and the linearization circuit in the low-gain mode.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus comprising: a first amplifier circuit coupled to an amplifier input; a second amplifier circuit coupled to the amplifier input and in parallel with the first amplifier circuit; and a linearization circuit coupled to the amplifier input, the first and second amplifier circuits being enabled in a first mode, one of the first and second amplifier circuits being enabled in a second mode, and the linearization circuit being enabled in the second…
