Abstract
Official abstract text for this publication.
Apparatus and methods for electronic amplification are provided. In one embodiment, an amplifier includes first and second input terminals, an amplification circuit, a feedback circuit, and a current mirror. The amplification circuit includes a non-inverting voltage input electrically connected to the first input terminal and to a bias voltage, an inverting voltage input electrically connected to the second input terminal, a voltage output, and a current output. The amplifier includes a first feedback path from the voltage output to the inverting voltage input through the feedback circuit and a second feedback path from the current output to the inverting voltage input through the current mirror, which can mirror a current from the current output to generate a mirrored current. A current source such as a transducer can provide an input current between the first and second input terminals, and the mirrored current can substantially match the input current.
First claim
Opening claim text (preview).
What is claimed is: 1. An amplifier comprising: an amplification circuit comprising a first voltage input, a second voltage input, a voltage output, and a current output, wherein the amplification circuit is configured to control a voltage level of the voltage output by amplifying a voltage difference between the first and second voltage inputs, and wherein the amplification circuit is further configured to generate a first current on the current output based on the voltage diffe…
