Abstract
Various technologies described herein pertain to variable gain amplification for a sensor application. A multistage variable gain amplifier system provides variable gain amplification of an input signal. The multistage variable gain amplifier system includes a plurality of amplification stages. The multistage variable gain amplifier system further includes a power detector configured to detect a power level of an input signal received by the multistage variable gain amplifier system. The multistage variable gain amplifier system also includes a controller configured to control the amplification stages based on the power level of the input signal. The multistage variable gain amplifier system can output an output signal such that the amplification stages are controlled to adjust a gain applied to the input signal by the multistage variable gain amplifier system to output the output signal.
