A ratioless and biasless static CMOS level shifter

A CMOS level shifter is presented that has no static power dissipation (biasless) and does not rely on MOS device sizing for basic operation (ratioless). Propagation delays for fabricated circuits are presented over a supply range of 5.0 Volts to 0.8 Volts. The proposed level shifter is intended for Scalable CMOS digital libraries and low-power automated test equipment.
