Abstract
A receive signal strength indicator circuit includes a low-noise amplifier, an envelope detector, and a selection circuit. The low-noise amplifier has a plurality of serially-coupled amplifier stages each providing an amplified signal, wherein a first amplifier stage receives an input signal whose signal strength is to be measured, and a last amplifier stage provides an amplified output signal. The envelope detector stage includes a plurality of envelope detector circuits, each having an input receiving the amplified signal of a corresponding one of the plurality of serially-coupled amplifier stages, and an output for providing a receive signal strength indicator component. The selection circuit is coupled to the outputs of the plurality of envelope detector circuits, and provides the receive signal strength indicator component of one of the plurality of envelope detector circuits having a desired linear range as a detected RSSI signal.
