Abstract
Certain aspects of the present disclosure generally relate to a multi-output amplifier implemented using a capacitive attenuator. For example, the multi-output amplifier generally includes a first capacitive attenuator coupled to an input node of the multi-output amplifier. In certain aspects, the multi-output amplifier also includes a first amplification stage having an input coupled to a tap node of the first capacitive attenuator and an output coupled to a first output node of the multi-output amplifier, and a second amplification stage having an output coupled to a second output node of the multi-output amplifier. For certain aspects, the multi-output amplifier includes a second capacitive attenuator coupled to the input node of the multi-output amplifier, and the second amplification stage may have an input coupled to a tap node of the second capacitive attenuator.
