Design of Bandgap voltage reference (BGR) - 11 : Design of start up circuit for BGR

[@prakhartandon3887]

HI sir , you described BGR in a very conceptual way. Please upload a lecture regarding folded cascode opamp.

[@Sourav_Soumyajit]

Excellent

thanks for the video! can we use the same start up circuit for both current mirror and op-amp topology? why do we need to use different start up circuit for each?

[@anantheshkv6787]

In the start up circuit, you have used one current mirror with NMOS pair to switch off the PMOS after disturbing the 0 volt condition. Great till this point. After this, why we are not switching off the current mirror and the NMOS of the start up circuit in the normal operation. This will consume unnecessary power right?

yes. it is better to switch off. i just showed one simple circuit as an example
