Abstract :
This paper describes the DC and high frequency characteristics of a low-cost, 0.15 /spl mu/m PDSOI DRAM technology. A compact dynamic threshold (DT) device design in this process is found to be superior to both grounded body (GB) and floating body (FB) PD-SOI MOSFETs. This device achieves kink-free behavior, with gm=936 /spl mu/S/um, g/sub out/=36 /spl mu/S/um, Ion/Ioff=210 /spl mu/A/0.1 pA, S=67 mV/dec, and fmax=32 GHz at V/sub DD/=1 V. These DTMOS devices are excellent for sub-volt embedded baseband and IF circuits and sufficient for RF front-end circuits, thus enabling the combination of embedded DRAM, digital, analog and RF circuit cores in, ultra-low-power, low-cost SOCs.
