Abstract
A signal buffer amplifier with high linearity is provided. A circuit includes a first transistor having a first gate terminal, a first source terminal, and a first drain terminal. The circuit also includes a second transistor having a second gate terminal, a second source terminal, and a second drain terminal, the second drain terminal coupled to the first source terminal. The circuit further includes a first signal path coupled in between a signal input and the first gate terminal, a second signal path coupled in between the signal input and the second gate terminal, and a signal output coupled to the second source terminal. The first signal path includes a filter.
