Analysis of Two New Voltage Level Converters With Various Load Conditions

Abstract

The use of level converter in dual supply voltage circuits is one of the most effective ways to reduce power consumption. To prevent static current, level converter is introduced as an interface at each low-to-high boundary. The design of an efficient level converter with least power consumption and overheads delay is one of the major design constraints. In this paper, two new level converter circuits with low power consumption are proposed for less propagation delay and load adaptability. The proposed level converter circuits are examined using cadence and the design parameters of a 180 nm CMOS process. The simulation results exhibit that proposed level converter can reduce propagation delay and increase speed over the existing circuits available. These level converters are simulated for different loads and operating conditions. The proposed level converter can operate at different values of V DDL as +1 V, +1.8 V, +2 V and V DDH of +3.3 V. The topology reports low sensitivity and has features suitable for VLSI implementation. The proposed circuits are suited for low power design without degrading performance.
