Abstract :
An all-CMOS output buffer has been developed. The output buffer is composed of a voltage-follower and a source-follower circuit. The performance of the output buffer is characterized by a low-voltage operation of 1.7 V, a short delay of 1 ns, availability for the wired-OR connection, and adjustability to TTL, ECL, and a reduced swing level (RSL). The output buffer is incorporated into a 64-kb CMOS SRAM. This SRAM has achieved an access time of 4.3 ns at a supply voltage of -3.6 V
