Abstract: An embodiment of an amplifier circuit includes first, second, and third amplifiers. The first and second amplifiers, each of which can be a respective operational amplifier or a respective transconductance amplifier, are configured to amplify a differential input signal with a non-inverting gain. And the third amplifier, which can be an operational amplifier or a transconductance amplifier, is configured to cause the first and second amplifiers to amplify a common-mode input signal with a gain that is less than unity. The third amplifier can also be configured to cause the first and second amplifiers to generate a common-mode output voltage that is substantially independent of the common-mode input voltage. Consequently, in addition to presenting a high input impedance and a low noise factor, such an amplifier circuit has a configurable common-mode output voltage and has a lower common-mode gain (e.g., less than unity, approaching zero) than other non-inverting differential amplifiers.

Abstract: A redundancy network is coupled to a first plurality of signal components and to a beam hopping network. The redundancy network has redundancy network signal junctions configurable to define redundancy network signal paths through the redundancy network, with one path for each signal component. The beam hopping network has beam hopping junctions configurable to define beam hopping signals paths from the redundancy network to other signal components. The beam hopping junctions are dynamically adjustable to reconfigure the beam hopping signals paths so signals from the redundancy network are deliverable to at least two of the other signal components. The redundancy network signal junctions are reconfigurable in response to a failure of one of the first signal components to redefine the redundancy network signal paths so that signals from the remaining first signal components are distributable, by the beam hopping network, to all of the other signal components.
