Abstract
The design and performance of a 2 Kbit sine-cosine ROM lookup table in 0.3 μm gate length AlGaAs/GaAs/AlGaAs HEMT technology are presented. A maximum clock frequency of 1.3 GHz is achieved resulting in a sub-nanosecond access time. The power consumption at supply voltages of +1.8 and -2 V is ~2 W
