Abstract :
Dual-gate GaAs MESFET logic has been used to develop a monolithic variable-modulus (/spl divide/10//spl divide/11) counter. The circuit incorporates a novel feedback design that will allow the counter to operate up to the maximum speed of its flip-flop components, which have demonstrated cutoff frequencies above 2.5 GHz. The full counter has operated to 1.6 GHz while mounted in a coplanar test fixture. Operation above 2 GHz is expected when a test fixture with reduced crosstalk is used.
