    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?

    Understanding two Multivibrator models

    Hello, I simulated the two multivibrator models in CMOS technology using the cadence tool. I was expecting the model 2 with Schmitt trigger(ST) will show robustness in PVT (Process Voltage temperature) analysis as compared to model 1 due to ST. But this was not the case both the Models shows the...

    What is Cmeu in an npn BJT operating in saturation mode ?

    I know Cmeu is parasitic capacitance in active mode. It's the B-C junction capacitance. But does it change when the npn is operating in saturation mode? Also in general(not just in saturation mode) what happens to Cmeu at increasing Vce? Does it increase? What other things happen to the...

    How to connect E3JM-R4S4 PNP Sensor

    Hi, this is E3JM-R4S4, brown and blue connect to power supply. I wanted to know is it either black or brown connect to +load and the white connect to 0V? If is it so, I don't see the electric flow.
