0.7 V Manchester carry look-ahead circuit using PD SOI CMOS asymmetrical dynamic threshold pass transistor techniques suitable for low-voltage CMOS VLSI systems

The authors report a 0.7 V Manchester carry look-ahead circuit using partially depleted (PD) SOI CMOS dynamic threshold (DTMOS) techniques for low-voltage CMOS VLSI systems. Using an asymmetrical dynamic threshold pass-transistor technique with the PD-SOI DTMOS dynamic logic circuit, this 0.7 V PD-SOI DTMOS Manchester carry look-ahead circuit has an improvement of 30% in propagation delay time compared to the conventional Manchester carry look-ahead circuit based on two-dimensional device simulation MEDICI results.
