Abstract
A resistively folded single stage differential amplifier capable of accommodating a low input common mode without impacting the performance of a bias current source, while also providing a high input impedance to allow for the use of the linear termination resistors. The differential amplifier provides an amplified output signal with a common mode referenced to an upper bound of an input power supply. The differential amplifier includes an input sub-stage and a transistor sub-stage resistively folding the input sub-stage.
