Abstract :
Certain logic functions such as the control units of VLSI processors are difficult to implement by random logic. Since the programmable logic arrays (PLAs) can implement almost any Boolean function, they have become popular devices in the realization of both combinational and sequential circuits. We present a low-power high-speed complementary-metal-oxide semiconductor (CMOS) circuit implementation of NOR-NOR PLA using a single-phased clock. Buffering static NAND gates are inserted between the NOR planes to erase the racing problem and shorten the duration of glitches such that the dynamic power is reduced in addition to the low static power dissipation, no ground switch, no charge sharing, and zero offset
