    how to make capacitor unchange under different process?HELP

    I spent mach time for this problem, and faund that it is imposible. But you can try nmos cap.

    PWM and PFM advantages ? differences in Boost converter apps

    advantages and disadvatages of pwm Usualy for low current (<300mA) uses PFM. But remember about limitation currents passed thru power PMOS or NMOS.

    oscillator IC desgin with CMOS process, internal Cap

    Dear all. In my process (0.6u 25HV option) I use nmos Cap. By simulation (Cadance) I have 5% accuracy. In SPICE distortion of Tox by corners arround 4%. In reality on wafer will I have this accuracy or not? Sambody have experience in it? P.S. I use HV NMOS CAP (Tox=690 +/-30A) TNX beforehand.

    mosfet as a capacitor

    A whot about accuracy? And from whot it depend? TNX!
