hello
i want to change the swing of a signal from 0 -->1.8 to 0 -->3.3,,i tried using nmos transistor as a switch putting the signal on its source,,1.8 bias on its gate and 3.3 supply to the drain through resistance,,taking output from the drain,,it works well but when i decrease the frequency,,it didnt work well,,,note that i am operate at 1 Gbps,,can anyone suggest me a way to change the swing or even tell me the drawbacks of what i mentioned above....thanks
