I am using Arduino DUE for my project which gives a 3.3 volt output signal. I have to convert it to 5 volts to use it with another device. The problem is that my signal frequency is 1 MHz. I have tried using Spark Fun logic level converter which uses BSS138 MOSFET. The converter does give a signal of 1MHz but its output amplitude remains at 3.3 volts. I need to convert it to 5 volts. Can anyone tell me whats the problem. Why the signal amplitude remains at 3.3 volts? I have also tried the same circuit with 2n7000 MOSFET but it also gives the same problem. If frequency is the problem then can anyone suggest a level converter or circuit that can convert the 3.3 volt signal to 5 volts at 1MHz. Thank You
