i have a problem of how to design a resistor network to generate the needed voltage by using as few squares as possible. is there any normal procedure to do this? or depending on the experiences of the designer?
i wish there are some reference books to me. if you have any advice i will very happy. thans very much!
Use a unit resistor so that every output voltage can be selected on the terminal of one single unit resistor. For example, choose your unit resistor si that you have 100mV acros its terminals. So, you can have 2V across 20 unit resistors, 3V with 30 resistors, etc.
your method depends on the wegiht. and, can not get the quite arbitrary&multiply output voltages. for example, i want to get a output of 1.61V and 2.05V. in this case, your strategy is disable.
