Claims
- 1. A multi-stage receiver for a radio frequency signal, comprising:a first amplifier, having a first bias level, configured to receive a radio frequency input signal and amplify the same into a first internal signal; a second amplifier, having a second bias level, configured to receive the first internal signal and amplify the same into an output signal; a detector configured to receive a radio frequency signal indicating a signal strength of the input signal including signal strengths of jamming signals received with the input signal and produce according thereto a bias control signal; a first bias generator configured to receive the bias control signal and generate according thereto the first bias level; a second bias generator configured to receive the bias control signal and generate according thereto the second bias level; a local oscillator and buffer, having a third bias level, configured to generate an intermediate frequency signal; and a third bias generator configured to receive the bias control signal and generate according thereto the third bias level.
