About boost converer, ask two quesiton,thanks
1. How much boost's max duty can reach generally? Can it exceed 90%? such as Vin=3V to Vout=30V.What it pay attention to?
2. Now I design a boost, typ duty is 32%(Vin=3.8,Vo=5.6), uttermost is 60%. Frequency is about 1.5M, or below(800K).
My...
In my buck DC-DC project, Power PMOS is bought and adpoted,that
s to say, only design controller. Add pmos model when Top simulation.
Now a question come on. In top simulation, SW signal time of rising match with test result (base on tapeout samples), but time of falling more than test...
This is an error amp.What's the purpose of resistance at base? Is it should
increase first stage' load resistance and so increase the gain? others?
Thank you very much
Introduction
There are many benefits which result from the use of
feedback in electronic circuits, but the drawbacks are the
increased complexity of the calculations and the opportunity
for the resulting circuit to ring or oscillate. This paper employs
graphical techniques to simplify stability...
This is the structure of AMP,its principle as follows: A voltage is 100mV(divided from VERF) when chip out hasn't current. PIN change more negative when current increase, and A decrease to zero voltage when over current coming. From now on, this amp begin to work to control the out.
My question...
This is input construction of OTA. PIN is negative (change as out current), Once A drop to zero, OTA begin to work. My question: why Q1/2 collector is connected to Q3/Q4 collector. consider what? Q1/Q2 act as lever shift. they can connet gnd directly, I think. Thanks for your relply!
