Abstract
A radio frequency (RF) receiver circuit is disclosed. The RF receiver circuit includes a variable gain amplifier, configured to receive an input RF signal, and to generate an amplified RF signal based on the input RF signal, where a gain of the variable gain amplifier is variable. The RF receiver circuit also includes an RF level indicator circuit, configured to sample the amplified RF signal at non-periodic sampling intervals to generate a plurality of sampled RF signals, and to compare the sampled RF signals with one or more thresholds to generate a plurality of comparison result signals. The gain of the variable gain amplifier is determined based at least in part on the comparison result signals.
