High-Voltage Square Wave Generation, How?

[yousif]

How can one design a High-Voltage (0 to >100V) Square Wave ( OR Bit Pattern) with frequency form DC to many KHz

I Found this paper but it is not for public use :

Something like this : http://www.avtechpulse.com/high-voltage/av-112ah/sn11846,AV-112AH-PS.pdf

For bipolar pulses:
1. a high voltage operational amplifier or
2. a high voltage bidirectional constant current generator and mirror the input pulse

For unipolar pulses:
- use a high voltage oped drain circuit

Thank you but your solutions require high voltage source whether for the opamp or the transistor, and the problem here is that I need to control the output voltage level !
