    Channel Length for Analog Design

    You also need to see the variation of Vt with length. Choose the length where the vt variation is minimum. Same thing is applicable to width also. After arriving at good width and lengths, we can use multiple transistors to increase the drive. Try to use even number of transistors fo better...

    bandgap generator at low supply

    hi all, Gve me an idea to generate a bandgap reference voltage from low supply voltages, say 1.6v. Is it possible to generate bandgap ref. voltage from 1.2v supply?

    Can I make a MOS transistor's width longer than its length?

    Re: Can I make a MOS transistor's width longer than its leng Definitely W can be more than L of a transistor. In any semiconductor technology there will be minimum length and widths possible for manufacturing. With technology shrinking(people will be talking of 90nm, 65nm and recently 45nm...

    Glitches in crystal oscillator output

    Thank you sir, Higher harmonic terms are not only low in amplitude but also they can be suppressed by subsequent comparator when designed with proper bandwidth. But I worry if there are any chances of getting glitches at comparator output .. say due to supply noise or sudden decrease in...

    Glitches in crystal oscillator output

    The sinusoid output of crystal oscillator is converted to square wave with a comparator. I want to know if there is a possibility of glitches at the output of crystal oscillator.
