Paul Brokaw formulated the following practical rule: if on the circuit diagram one can draw a closed line around the supply bus that crosses only drains of MOS devices or collectors of bipolar transistors, then such circuit has the second stable condition when all components are off [106]
[106]. P. Brokaw, “Bandgap reference design”, MEAD Microelectronics Class on Power Management, Lausanne, 2003.
In a book I read a comment on start-up circuit, but I just can't figure what did the author mean by "draw a closed line around the supply bus that crosses only drains of MOS devices or collectors of bipolar transistors,"
Some one understand plz explain it to me.
Besides anybody offer the ref[106] will be really appreciated.
