    Overshoot spike at falling edge in response of a PI-controlled laser system.

    The output of a photodiode is used as the feedback signal of a laser intensity control loop. The controller currently implements PI control, and the laser together with the optical path forms the plant transfer function. When a step change is applied to the system, the photodiode output shows...

    Resistor and capacitor order dependent noise in the output signal (measured with a handheld oscilloscope) of an RC circuit

    Hi. I have an RC circuit 1kOhm and 22uF that generates a sine wave from a PWM signal generated by a battery powered STM32F103C8T6 (Blue Pill). I take all measurements with a handheld oscilloscope (battery powered). The PWM frequency is 10kHz. I noticed that the connection order affects my...

    overshoot and stability issue

    Hello, I have designed a two stage op amp with a phase margin of 63° ( with a compensation capacitance) which is sufficient to ensure good stability of the circuit. However, I still have a huge overshoot problem when I use it as a follower. How is it possible if my circuit is stable and how can...
