hv amplifier
Hello.
Does anybody have any idea, how to build an amplifier for a piezoceramics? I need to have 150V at output, max output current <10mA, SR > 1V/µs. The input voltage will be in 0...5V range, so I need the gain G=30.
The problem is I don't know how to design the output stage. Most probably there will be low voltage IC amplifier, and some transistors connected to high voltage (c.a. 160V). Can anybody make a sketch of it, or give an interesting link?
