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.

Signal buffer amplifier

In one embodiment, a circuit for generating a reference voltage between a first output and a second output, has a first follower transistor that includes a first control node, a first follower node coupled to a first output, and a first supply node, and a second follower transistor that includes a second control node, a second follower node coupled to a second output and a second supply node. A first voltage drop circuit is coupled between a circuit supply node and the second supply node. The circuit is biased such that the voltage between the circuit supply node and the second supply node is greater than the voltage between the circuit supply node and the first supply node, and such that the voltage between the circuit supply node and the second control node is greater than the voltage between the circuit supply node and the first control node.
