A 0.3V 3.6GHz 0.3mW frequency divider with differential ED-CMOS/SOI circuit technology

A differential ED-CMOS/SOI circuit combines both zero V/sub T/ CMOS/SOI and ED-MOS/SOI circuits and operates at supply voltages as low as 0.3V. An experimental frequency divider, fabricated in a 0.25/spl mu/m fully-depleted SOI process, achieves a maximum operating frequency of 3.6GHz at 0.3V and 5.4GHz at 0.5V while reducing power dissipation to less than 1 mW.
