Popis
Shrnutí:	This paper describes a 16 /spl times/ 16 bit single-cycle 2's complement multiplier with a reconfigurable PLA control block fabricated in 90-nm dual-V/sub t/ CMOS technology, operating at 1 GHz, 9 mW (measured at 1.3 V, 50/spl deg/C). Optimally tiled compressor tree architecture with radix-4 Booth encoding, arrival-profile aware completion adder and low clock power write-port flip-flop circuits enable a dense layout occupying 0.03 mm/sup 2/ while simultaneously achieving: 1) low compressor tree fan-outs and wiring complexity; 2) low active leakage power of 540 /spl mu/W and high noise tolerance with all high-V/sub t/ usage; 3) ultra low standby-mode power of 75 /spl mu/W and fast wake-up time of <1 cycle using PMOS sleep transistors; 4) scalable multiplier performance up to 1.5 GHz, 32 mW measured at 1.95 V, 50/spl deg/C, and (v) low-voltage mode multiplier performance of 50 MHz, 79/spl mu/W measured at 570 mV, 50/spl deg/C.
