A Quick and Power Efficient Controlled Voltage Level-Shifter using Cross-Coupled Network
2021
This concise presents a quick and power efficient level-shifter (LS) using cross coupled network. This technique will eliminate the drawbacks of conventional LS using cross coupled network in the pull up region, this will make circuit to run fast and power required is also reduced. Compared to previous LS's the proposed level-shifter consists of less number of elements and their sizes are comprised to minimum, this will decrease the area of LS. The existing LS cannot convert voltages below V TH and the voltage range offered is less and power utilization is more. In order overcome this with the use of crosscoupled network in the pull up region, the high switching speed achieved. By decreasing the transistor size, voltages are converted below V TH and energy utilization is decreased. To design a high speed and low power LS by using RCC in pull up region. It is used in low power applications such as implantable medical components. Proposed level-shifter functions effectively with less delay for inputs below the sub threshold voltages. For simulations LT spice tool of 180nm technology is used. The total delay and power utilization of the proposed voltage LS for 0.4V/1.8V and 1 MHz are 21ns and 76.34nW.
