As follows, fig1 shows in the tag, there is a limiter after dickson charge pump, to limit the supply.
Fig2, can we assume the limiter as some diodes? It means that, if the limiter do work, we can regard it as a small resistor which in parallel with the system, thus the voltage of the system is limited.
Fig3 is the circuit of dickson charge pump.
So, is it necessory to add a clamp in fig1? (All the transistor must operate below 3V.). If the clamp is needed, what's the reason and its influence?
Thanks for your reply very much
