Hey guys!
I was trying to build a circuit to regulate the voltage between an ADC to the RS232 port of an FPGA. The voltages outputted by the ADC are at 0V (for logic 0) to 5V (for logic 1). These voltages need to be shifted/multiplied to -6V (for logic 0) to 6V (for logic 1). I was thinking of using a voltage multiplier circuit but I don't know how to shift the voltage from 0-5V to -2.5-2.5V. Can anyone help me? And do you think I'm on the right track?
Thanks,
Anup
