    Open drain NMOS - how does it work?

    Re: Open drain NMOS Thanks for the reply!! In both these cases, does NMOS operate in saturation(active) or linear(triode) region? And how is it biased?

    Open drain NMOS - how does it work?

    Open drain NMOS usually in circuit design an interrupt signal is through an open drain nmos. In applications a pullup resistor is connected on this open drain to indicate an interrupt. I would like to know how does this open drain NMOS works. I tried looking online, however, could not...

    design of bandgap reference

    I designed a bandgap reference and plotted vref vs temp, i do not get the curve as is shown in all the text books. However, i get vref = 1.2V at room temp. Also i plotted the dvref/dt and do not get 0, at any temperature. I could not figure out what is wrong with the circuit. I am new to...

    Help me with my circuit - Bandgap reference

    Band gap reference I designed a Bandgap reference to have a Zero Temp co at Room temp (25 deg C). I get 1.2V at 25C, however, the plot of Vref and temp does not look correct. Also, i plotted d(vref)/dT, and at any temperature it does not cross 0. I am attaching a copy of my schematic, plot o...
