voltage translator 20mhz
I want to take the output of a 3.3v cpld and have it drive target
devices that may have various voltage standards -
(1/1.8/2.5/3.3/5 volts). The target voltage is available
as an input to the circuit. The circuit needs to operate at
20 MHz. I am trying to find a Simple circuit (e.g., 1 transistor
+ resistors) that will do this.
I've heard a common-base transistor configuration, with some
modifications will accomplish this. Also the delay should
be no more than 10 ns throught the translator.
All help is greatly appreciated.
