A Comparison of The Different Gaas Phemt Logic Families Characteristics

A comparison of the GaAs pHEMT logic families characteristics is presented. Six logic families were compared. A comparison showed that the use of high value resistors allows reducing the occupied area by 1.6 times and the power consumption by 5 times of the NOT gate for DCFL circuits. It was found that the use of such resistors in the BFL circuits allows to reducing the occupied area by 2 times and the power consumption by 2.5 times. Also, the characteristics of a DCFL circuit for the two foundries are compared.
