Abstract
A differential-input, differential-output CMOS amplifier having a first differential pair with a first transistor folded with a first cascode transistor, and a second differential pair with a first transistor folded with a second cascode transistor, and having a first auxiliary amplifier to provide negative feedback to the first and second cascode transistors to boost amplifier gain, where the first and second cascode transistors have gates at the same potential. The first differential pair has a second transistor folded with a third cascode transistor, and the second differential pair has a second transistor folded with a fourth cascode transistor, where a second auxiliary amplifier provides negative feedback to the third and fourth cascode transistors to boost amplifier gain, where the third and fourth cascode transistors have gates at the same potential.
