(1) quite some literature about BGR using MOSFET in weak inversion
instead of parasitic BJT. How do they behave in real product?
(2) we use LDO + BGR to avoid PSRR problem.
LDO output to BGR,
meanwhile input reference voltage of LDO
is taken from the output of BGR
We did check startup by transient.
But still wondering if this a good common practice?
Thanks in advance.
