Hi to all,
I am presently a part of research group. We are analysying various circuits to be used in a Wireless Sensor node..
We need to design a charge pump (Dickson Charge pump) that takes a input of ~0.2 V or ~ 0.3 V and converts into `2 V at the output.. We are using PSPICE to simulate the circuit.. (We may also use TSpice- if its useis warranted)..
The main problem is - we need a low Vt NMOS transistor model.. In fact, in some IEEE research papers, people have explored designs using zero Vt NMOS.. However, I cannot understand how we could have a zero Vt NMOs .. We a model is available for zero Vt or very low Vt NMOS, we would be helped to a great degree.
I tried searching at various places on the web,but did not find any such models..
1) Could anyone suggest what I should do?
2) Could anyone post any low Vt NMOS model ??
Thanking you all in advance,
