Low Power High Performance Baud Rate Generator using MTCMOS Voltage Interface Circuits

Multiple supply voltages (multi-VDD) is an effective technique for reducing the power consumption without compromising speed in an integrated circuit(IC). Different blocks of the design may be operated with different supply voltages. To transfer signals among the circuits operating at different voltage levels different level conversion circuits are required. Two types of Voltage Interface Circuits, feedback based and MultiVTH are implemented and used in the implementation of Baud Rate generator. The need for level conversion has delay and energy penalties. In this paper, the Voltage Interface circuits are individually optimized for minimum propagation delay. Baud Rate generator is designed and implemented using 90nm TSMC
