【電子工学/OPアンプ回路】028-1：OPアンプ（OPアンプをゼロから設計｜負帰還での発振原因とボーデ線図での安定判別）

[Overview] This section will examine the actual waveforms obtained when the simple operational amplifier designed in the previous document is assembled on a circuit board and operated as both an inverting and non-inverting amplifier. By changing the gain settings and negative feedback, we will intentionally create cases where oscillation occurs in addition to ideal amplification, and carefully explain the oscillation waveform and frequency characteristics using Bode plots. Furthermore, we will demonstrate how to read stability, such as phase margin, from the pulse response using measured waveforms, explaining the often difficult-to-understand operational amplifier stability design by correlating manual calculations with experimental results, making it intuitively comprehensible.
