    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...

    How to find out if UJT 2N2646 is original or not?

    I bought two UJT (2N2646) before yesterday. I tried to make an oscillator but it was not working. There was a guy from FB who said it could be a duplicate (not original) one. It must be tested. How should I test if it works or not. I googled some and found about diode and resister testing. But...
