Abstract :
This paper reports a 1.5 V bootstrapped pass-transistor-based carry look-ahead circuit suitable for CMOS VLSI using a low supply voltage. With the bootstrapped technique, the speed performance of a 4-bit carry look-ahead circuit can be enhanced by 70% at a supply voltage of 1.5 V as compared to the conventional Manchester carry look-ahead circuit
