Hello,
I have a question that maybe is very stupid but I'm loosing myself.
I have the DC power supply (Vdd) and I need a DC voltage of Vdd-3V for biasing a device. The current absorbion must be very low. My professor suggestion is to use 1 MOS and its Vgs but I don't understand how. I thought that he meant a mos connected as follow:
- drain to Vdd
- gate to Vdd
- source to the point where i want Vdd-3V
but it doesn't work as expected. Any suggestion?
Thanks
