A novel power on reset (POR) circuit with brown out (BO) detector having zero steady state current consumption is proposed. The circuit has been designed in 65nm CMOS process at a single supply of 1.1V. Both the POR and BO thresholds are independently adjustable in the circuit. Simulation results show that the POR threshold does not depend upon the supply ramp-rate at fixed process and temperature corner. BO circuit works for a large range of supply ramp down rates. Due to zero steady state current consumption, the proposed circuit is well suited for low power applications.
