Level shift + amplify


Let's say I have a signal where 1v is digital 0, and 4v is digital 1.



I am a little lost how can I use PNP+NPN transistor to have +11..12(for 1) or -11..12V(for 0) output, provided that I have +12/-12 PSU?


UPDATE: This is for low-power MOSFET driver, which has to be done in discreet transistors.

Is this what you mean? enter image description here

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
