Patent abstract
A buffer circuit comprised of two matched stages is provided. The first stage develops a replica voltage that is used in the second stage as the input to a wide-band amplifier. The combination of the two feedback loops in the circuit result in improved linearity. The first amplifier dominates for moderate frequencies while the second amplifier takes over for high frequencies.
