ABSTRACT:
A circuit is disclosed which responds to an input voltage signal for adjusting the voltage applied across electrodes of an electro-optic modulator. The circuit includes two FETs connected in series. These FETs are operated as voltage controlled variable resistances. The electrodes are connected in parallel across one of these resistances. These resistances are vary in response to the input voltage signal to change the voltage applied across the electrodes. The circuit draws low current while providing sufficient bandwidth for exposing high quality images.
