PEAKING CIRCUIT, PEAKING CIRCUIT CONTROL METHOD, WAVEFORM MEASUREMENT APPARATUS, AND INFORMATION PROCESSING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a peaking technique suppressing the influence on the amplification degree of a low-frequency area when changing a peaking amount. SOLUTION: The peaking circuit includes: amplifier circuits connected in multiple stages; and feedback circuits for feedback to an input side from two or more output points with different amplification degrees when viewed from the input side, and is configured to be able to change an amount of feedback of the feedback circuits.
