how to increase the voltage

[mtc2629]

Hi everybody i was just wondering how to increase the voltage of a signal.Like 1v to 30v but the same signal the problem is i dont want to blow up any components or really thin wire but i still want the same out put. For example if it gave out a high,low,low,high,low then a high i want it to be the same but a higher voltage
Thanks

So you are looking for a DC-to-DC power supply? one way of doing this is known as a boost converter
see: http://en.wikipedia.org/wiki/Boost_converter

However, this might not be the best answer to your question. Could you provide any additional information?
Do you only have a single power source?
What is the load?
How much power is required and how much is available? (power = volts x amps)

What is this signal coming out of? And do you already have this 30v available somewhere else in the system that you can use?
If I understand right, you want to be able to increase the amplitude of a signal from some kind of IC, and you already have the higher voltage available, therefore you can use almost any transistor or MOSFET, or even a relay if your signal is slow.
Can you tell us more about the system?
