Abstract :
The proposed output buffer circuit uses 1.8V transistors in 90nm CMOS process to develop I/Os for 2.5V and 3.3V interfaces. A voltage clamp circuit, bias generators, and a feedback circuit are used to ensure reliability and noise decoupling. Use of these circuits enables achieving low power (130μA) and high performance (up to 275MHz) in a comparative area of an equivalent I/O in 90nm 3.3V process.
