Abstract
A high-speed swtich driver provides a precise output voltage swing for microwave switches. A first embodiment is for use with TTL circuits, and includes alternating high-gain voltage level shift and differential amplifier stages. A second embodiment also includes alternating voltage level shift and differential amplifier stages, but further has the flexibility to be used with a variety of logic circuits, including TTL, ECL, differential ECL, CMOS any circuit requiring user-defined input levels. Both embodiments provide complementary outputs at voltage levels that may be set by the user.
