I need design a bandgap reference of 2.485V or so ,my boss said he need torlerance is ±2mv ,i can't reach it beacause The TC≈4ppm at 2.485v bandgap reference ,at the same time ,temperature -40~125,vcc 4~6.5 ,PSR about 100ppm..
although the bandgap cann't be desgin ,but i want to try my best to design the bandgap . The voltage reference is based on pure mos techonlogy ,only pnp and mos are achieved.
please veteran give my some advice , books or structures about high voltage bandgap voltage reference .thanks a lot.
