Abstract
Apparatus and methods for electronic amplification are provided. In one embodiment, a method includes providing a first differential amplification block, providing a second differential amplification block, electrically connecting the first and second differential amplification blocks in a stack between a first voltage reference and a second voltage reference, amplifying a first signal using the first differential amplification block, and amplifying a second signal using the second differential amplification block. A voltage difference between the first and second voltage references defines a power supply voltage, and the first differential amplification block operates over a first range of the power supply voltage and the second differential amplification block operates over a second range of the power supply voltage.
