High-Speed GaAs SDFL Divider Circuit

High-speed divider circuits find numerous applications in prescalers for counters, frequency synthesizers, and digital phase locked loops. To accommodate these applications, a high-speed multimode divider circuit has been designed, fabricated, and tested. This circuit, fabricated on semi-insulating Gallium Arsenide substrates, and utilizing Schottky diode FET logic (SDFL) technology, has been tested at a maximum clock frequency of 1.84 GHz. High yields of circuits operating over 1 GHz have been obtained over a number of wafers.
