ABSTRACT:
The receiver is provided which comprises a mixer, a low pass filter coupled to the mixer and a plurality of gain controllers serially coupled to an output of the low pass filter (LPF). A plurality of analog-to-digital converters (ADCs) is coupled so that an input of a first of the ADCs is coupled to the output of the LPF. An input of each of a remaining portion of the ADCs is individually coupled to a corresponding output of each of the serially coupled gain blocks. An output path traced from the output of the LPF to an output of each of the analog-to-digital converters may be referred to as a processing path. Each processing path may comprise a gain controller and an ADC, except for the first processing path, which may have an ADC coupled directly to the output of the LPF.
