Rapid Low Power Voltage Level Shifter Utilizing Regulated Cross Coupled Pull Up Network

In this concise, ultra low power and high speed voltage or logic LS circuit is introduced. With the help of regulated cross coupled structure in the pull up region the power utilized by the circuit is considerably decreased and speed of the circuit is also increased. The LS can convert the input logic levels or voltages below the V
TH
of the transistor to the higher acceptable levels. A LS requires less area because it consists of less number of components which makes it fit for low power and high speed applications, for example implantable clinical gadgets and remote sensor organizations. Tool used for simulation is LTspice 180nm technology. The LS can shift the input voltage or logic levels as less as 80mv to higher acceptable levels. The power utilized by LS is 149.5nw and propagation delay is 23.7ns.
