Abstract :
Partially depleted (PD) SOI has a number of nonideal effects due to the floating body: parasitic bipolar action, history dependent threshold voltage and logic delays, and the `kink´ effect. One must design around these effects in digital circuits so as to avoid circuit malfunction. This paper reviews the circuit design issues in PD-SOI CMOS technology. Realistic circuits from our design vehicle, a 32-bit PowerPC fixed-point execution unit, are included in the evaluation of the various circuit design alternatives. HSPICE simulations have been performed using a 0.25 μm SOI process and a bulk process
