【電子工学/OPアンプ回路】033：発振対策（OPアンプの低利得増幅回路は本当に安全か？｜ボーデ線図から読む発振の可能性）

[Overview] This video re-examines the stability of the simple op-amp built using the 028-1 document. We will carefully examine how the oscillation suppression measures, achieved by connecting a small capacitance capacitor in parallel to the feedback circuit resistor for phase compensation, are effective, using the waveforms of the sinusoidal input response and step response, as well as the Bode plot. We will also explain how to determine if the op-amp used is truly oscillation-free when used as a low-gain amplifier circuit, and what to look for to make that determination. [What you will learn in this video] ・The meaning of phase compensation by adding a parallel capacitor to the feedback resistor ・Signs of oscillation that can be seen from a sine wave input and step response ・How to check phase margin and stability by reading Bode plots ・Conditions under which a low-gain op-amp amplifier circuit may oscillate and how to identify it [Target audience] ・Those who want to properly check the stability of op-amp circuits ・Those who want to understand phase compensation as a countermeasure against oscillation in detail ・Electrical and electronic engineering students who want to learn stability determination using Bode plots ・Beginners to intermediate users who want to grasp analog circuit design from the basics [Video content] ・Explanation of a phase compensation circuit with a parallel capacitor to the feedback resistor ・Waveform observation and oscillation confirmation when a sine wave is input ・Stability of the amplifier circuit as seen from the step response ・Procedure for determining phase margin, gain margin, and stability using Bode plots ・Conditions under which oscillation may occur in a low-gain op-amp amplifier circuit [Series] 028-1: Op-amp (Designing an op-amp from scratch | Negative feedback) 　　　　(Oscillation Causes and Stability Determination using Bode Plots)    • 【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...   Video List: Electronics/OP Amp Circuits    • 【電子工学ENG】[OPアンプ回路]   #OpAmp #PhaseCompensation #OscillationPrevention #AnalogCircuits #ElectronicCircuitIntroduction #BodePlot #DIYAmp #NegativeFeedbackCircuit #CircuitStability #StepResponse
