The figure is a high-speed voltage follower circuit. The circuit is constituted by the VT3 and VT4. Al is the voltage follower circuit, which is constituted by the pin 7 of A1 and pin 4 of VT2 and VT6. Pin 7 of and pin 4 are just level shifting positions of the input signal voltage. Therefore, when the input signal is large, the power supply voltage on all-aspect of A1 and output end remains constant about 5V. As signal current through phase compensation capacitor from the Al-chip surges, the conversion rate has been greatly improved and high frequency distortion has been significantly reduced.
