58-82 GHz 4: 1 dynamic frequency divider using 100 nm metamorphic enhancement HEMT technology

The design and performance of a dynamic divider by four based on a 100 nm metamorphic enhancement HEMT technology operating in the range 58 to 82 GHz is presented. To the knowledge of the authors, this is the highest operation frequency obtained for a dynamic divider based on HEMT technology. The complete circuit has a power consumption of approximately 500 mW for a supply voltage of -3.5 V The input signal is single-ended. The output driver is able to drive a 50 /spl Omega/ external load.
