    transistors out of saturation in an op amp

    Hello, what would happen if, in my operational amplifier, some transistors are not in saturation at a certain input voltage? I find it quite hard, nearly impossible, to maintain tall the transistors in the saturation region for every input voltage, some of my transistors leave the saturation...

    NAND gate TTL - How it works

    Hello, I am studying digital electronics and I am a bit confused about the saturation conditions of the bjt. I knew that the bjt saturates when the Vce is close to 0 and Vbe >= 0.7. However, when I was reading about TTL I got confused. Can someone give me some intuition and explain me why in the...

    Switching response of an inductor

    I am experimenting with an inductor to see what is happening when it gets saturated and at which current it happens. So I set up the attached test circuit and checked the current on the 1Ω resistor. I expected the current to ramp up until the inductor gets saturated and then to increase at even...

    Calculation of Psat in cadence

    Hi, I am trying to figure out the Output saturation power of an amplifier for different frequencies of operation. I am using the PSS analysis in cadence and it only gives me 1dB compression point both input and output referred. Is there a way to find out Psat directly or from these values? I got...

    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...
