Method and system for loop through for multi-band TV tuners and set-top box and/or TV set applications

摘要

Methods and systems for loop-through for multi-band TV tuners and set-top box and/or TV set applications are disclosed and may include generating master and slave output signals from one or more low-noise amplifiers including master and slave stages. The master and slave stages may include parallel-coupled gain paths. Gate terminals and source terminals of input transistors for the master and slave stages may be directly coupled. The input transistors for the master and slave stages may share an inductor coupled to the source terminals and to ground. The master and slave stages may include cascode stages. VHF and UHF signals may be amplified in the multi-band receiver. The generated master output signal may be processed in the multi-band receiver, and may be utilized to generate I and Q output signals. A plurality of the slave output signals may be summed and communicated to a receiver external to the multi-band receiver.
