It is a nice books for bicmos design.
I find some bicmos book.it only discuss cmos "or" bipolar.
But in bicmos process,we need the cmos and bipolar device in one circuit (OPA.Comparator...)
You check these item.
1.The start up circuit in Internal voltage or current reference circuit
2.Current limit error. whe when power on suddenly , the inrush current (VIN) is so large (The current come from load(you sink 150~200mA) and Charge Co current.
You can check this item by rdeduce Co...
In POR1 ,When the AVDD with fast rising time,the POR wavrform maybe failure ( POR 2 Times)
The Cap in POR1 is 70fF,The MOS leakage will make POR1 failure in high temp.
POR2 is robust design.
In POR circuit design, You must check any VDD waveform in all application .
I have even study some book ,about ESD protection.
This ideal can let ESD MOS with good uniform turn on performance.
You can search some papers in JSSC.
This is a two stage amplifier.
the C1 and c2 are compensation cap.
the Compensation Pole in C2 is small than it in C1
,because the impedance of C2 is more than it in C1.
Note:please take care the DC bias of M23 M18
You can test dc spec. in (chamber )oven.
You can change temperature setting ,and measuren it.
You can decide the temp range by application environment.(-40~80 or 0~80 or -40~150..)
1.
I think that we do not need soft start circuit in charge pump circuit.
beacuse the flying cap is so small, in charge phase the inrush is so samll.
Note:Charge phase :the VIn charge flying cap.
Discharge Phase :Flying Cap discharge to Vo.
2.
The Soft Start purpose.
1.reduce...
1.The bulk of NMOS in P-sub N-Well Process ,it can link to vss(not source )
2.The gate of M17 link to BIASN
the V(CASN) maybe come form strat up circuit,not bias circuit.
3.Can you caeck the gate of M15 M16 in these condition.
I guess taht the start up circuit failure.
4.The satbility...
Re: read file~ hspice
You can use " .inc file_name "
The fisrt word of spice netlist can not be number .
The forst word "v " is for voltage source.
You have wrong format of "PWL "
You can check your netlist with spice user's guide.
