hi, can i ask a question here. i am new to bandgap design and have design a very simple brokaw cell without any opamp sensing circuit for feedback. i am facing a problem with a slow start up circuit, i am support to start up the circuit after 500ms but right now its 1s. The start up i use composes of a resistor and a few diode drops connected to the gate of a npn whose emiiter will drive the base of an npn. Anyone can give me some hints? Thank you very much.
