Abstract:
1. A method for dynamically adjusting a DC bias condition for a receiver system that is in communication with a broadcasting device via a communication link, the method comprising: generating an amplified signal with a low noise amplifier block in the receiver system in response to a broadcast signal received via the communication link; wherein the low noise amplifier block consists of a first low noise amplifier circuit and a second low noise amplifier circuit that are arranged in parallel; wherein a first side of a tuned circuit is coupled to a first input (INP) of the first low noise amplifier circuits through a capacitor circuit CIP, a second side of the tuned circuit is coupled to a second input (INM) of the second low noise amplifier circuit through a capacitor circuit CIN, wherein the first low noise amplifier circuit is arranged to provide a first output signal (OUTP) in response to the first input signal (INP), while the second low noise amplifier circuit is arranged to provide a second output signal (OUTM) in response to a second input signal (INM), wherein the low noise amplifier block further comprises resistor circuits RI
