Assignee: GM CRUISE HOLDINGS LLC
Field: Basic communication processes (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. A multistage variable gain amplifier system, comprising:
an input node configured to receive an input signal;
a set of N amplification stages, wherein N is an integer greater than 1, the set of N amplification stages comprises at least:
a first amplification stage; and
a second amplification stage;

a power detector configured to detect a power level of the input signal received by the multistage variable gain amplifier system at the input node;
a single pole, N throw switch; and
a controller configured to control the single pole, N throw switch to connect the input node at which the input signal is received to a particular amplification stage based on the power level of the input signal, the particular amplification stage being selected from the set of N amplification stages;
wherein the multistage variable gain amplifier system outputs an output signal such that a gain applied to the input signal by the multistage variable gain amplifier system is controlled to output the output signal; and
wherein the gain applied to the input signal to generate the output signal outputted by the multistage variable gain amplifier system is particular gain of the particular amplification stage selected from the set of N amplification stages.
