Kai, I apologize for the tone of my previous post. My reaction was mainly to this sentence: If you would connect C3 with the "-"-pin to GND, then V could never be higher than Vcc! This is simply not true; however, the way how it is drawn misleadingly suggests it. I was in doubts myself when I saw it yesterday; but I realized that C3's "negative" end is NOT connected to the pump itself. Now we can talk about inrush current, stresses, leaky capacitors etc.; we can model it in SPICE and test oscillator stability and startup, we can take samples from various manufacturers and various batches and perform measurements on them. But, the principles still remain the same. JW |
