Abstract :
A 4-bit Asynchronous multiplier was designed in the sub-threshold regime. The multiplier, using asynchronous completion detection, is more tolerant to process variation than conventional synchronous sub-threshold circuits and operates with a supply voltage as low as 150mV. The average energy per computation was simulated at 1.13pJ. The minimum energy voltage was simulated at 350mV, with an average micro-pipelined frequency of 11.3 kHz.
