Receiver system for e.g. mobile phone, has comparator circuit including positive input connected to output of detector stage, for comparing output signal of detector stage with reference signal, so as to provide demodulated output signal |
摘要 |
The system (100) has an amplifying stage (106) with an input connected to an input terminal (104), and an envelope detector stage (108) connected to an output of the amplifying stage. Another amplifying stage (110) includes a positive input to receive a reference signal (Swref). A comparator circuit (112) includes a positive input connected to an output of the detector stage, and a negative input connected to the positive input of the latter amplifying stage, to compare an output signal (Vout1) of the detector stage with the reference signal, to provide a demodulated output signal (Vdout). |
