Good evening, my name is Anass I am student in cycle Master at the university of fès in Morocco. I have a project of the end of studies on the charge pumps. I began to study the pump of Dickson and I have a problem at the level of the regulation of the pump. (I use the process AMI 06u)
The voltage VDD is equal in 5V I used four stage, the values of capacitors are 1 pF. the load is capacitive.
The frequency of clock is equal to 1 Mhz. I want to reach initially a voltage superior or equal to 10 V (the double of the power supply voltage). My question is the following one, how I has to compare the output voltage of the pump with a reference voltage?
Knowing that I have to try to make him(it) with an OTA-Miller the performances of which are:
Gain=70 dB, BW=2Khz, SWing OUTputmax=4.8 (VDD=5V, VSS=0V), ICMR=[1.5V;4.5V], PM=53° (CL=10pF, Cc=3pF)
Hi Anass -- no need to post in dual forums. I've passed your question along and I expect they will get to it soon. Also, another community member may help in the mean time.
Regards,
Nancy

Hi Anass -- Unfortunately, we can’t help with this. This gets in the realm of IC design. Maybe someone else out there knows...
