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