Bootstrapped application arrangement and application to the unity gain follower

A unity gain amplifier comprising:

• an input amplifier including a base to receive an input voltage signal;
• and
• an output unity gain buffer and a second unity gain buffer, the buffers configured to receive a signal from the input amplifier,
• wherein the output unity gain buffer is configured to provide an output voltage to an amplifier output, and the second unity gain buffer is configured to provide a bootstrap signal to the input amplifier.

An amplifier circuit comprising:

• an input amplifier including a first pair of complementary transistors arranged in an emitter-follower configuration, the input amplifier configured to receive an input signal at the bases of the first pair of complementary transistors;
• an output unity gain buffer configured to receive an output signal from the input amplifier and to provide an output voltage to an amplifier output utilizing a second pair of complementary transistors;
• and
• a second unity gain buffer configured to receive the output signal from the input amplifier and to provide a bootstrap signal to the input amplifier, the second unity gain buffer including a third pair of complementary transistors configured to drive the collectors of the first pair of complementary transistors.
