Abstract
A parallel output linear amplifier is provided that includes a transconductance amplifier configured to receive an analog input signal from an input terminal and amplify the analog input signal. The parallel output linear amplifier also includes a first pre-amplifier connected to the transconductance amplifier and operated using a floating drive voltage, and a cascode class AB amplifier connected to the first pre-amplifier and configured to provide an amplified signal to an output terminal. The parallel output linear amplifier further includes a second pre-amplifier configured connected to the transconductance amplifier and operated using the floating drive voltage, and a cascade class AB amplifier connected to the second pre-amplifier and configured to provide an amplified signal to the output terminal.
