Abstract: A biasing circuit is described for a radio frequency (RF) amplifier that provides a stable signal source. The described bias circuit has two or more transistors coupled in at least one feedback loop, with a buffering transistor providing the output biasing signal and buffering the feedback loops from the output of the of the biasing circuit. This arrangement provides thermal compensation, reduces fluctuations in the feedback loops that stabilize the biasing circuit, and allows for higher biasing current demand.

Abstract: Multi-tuner receivers with cross talk reduction are disclosed. In one embodiment, a multi-tuner receiver with cross talk reduction includes a low noise amplifier, a set of interstage filters and a set of corresponding tuners. In an alternative embodiment, a multi-tuner receiver with cross talk reduction includes a passive splitter, a set of interstage filters and a set of corresponding tuners. The interstage filters can be low-pass, high-pass or band-pass filters depending on the particular frequency range of interest. Typical embodiments can have two or three tuners, however, the invention applies to multi-receiver tuners with more than three tuners. The multi-tuner receivers can be used within television, cable set top boxes and other devices that receive multiple video signals.
