Abstract
High-performance radio frequency analog-to-digital converters (RF ADCs) demand high bandwidth, high linearity, and low noise input amplifiers. A Class-AB amplifier, including common-gate transistor devices and common-source transistor devices operating in parallel, offers high bandwidth and high linearity, while offering lower power operation when compared to Class-A amplifiers. The Class-AB amplifier can be followed by a Class-AB unity gain buffer comprising common-source transistor devices to provide additional isolation for the RF ADC from the circuitry preceding the Class-AB amplifier.
