    Parallel RC Circuit in Feedback Reading Line

    Hi, I'm reviewing an Evalboard datasheet and a parallel rc circuit is used in the feedback line, which I can't understand why, what is the purpose of this structure, whose image I have added below? Datasheet Link: https://www.nxp.com/docs/en/user-guide/KT33810UG1.pdf (Page 18)

    Single op amp PWM generator

    Hello, I have to design a single op amp circuit that has only +15v, -15v and GND as input and outputs a symmetrical PWM signal (+V and -V) with adjustable frequency and duty cycle. I have something that works partly but not completely, I can adjust the duty cycle from ±60% to ±100% but af that...

    How to find total current and phase shift for this Wien oscillator?

    I know that total impedance is Zp/(Zp+Zs) where Zp is parallel impedance and Zs is series impedance that can be calculated easily. Is total current equal to Vin/total impedance?
