Passive RFID circuits depend on low voltage low power area-efficient current references. This work presents two current source implementations using 180 nm CMOS process. Both circuits work with a minimum supply voltage of 0.8 V and with a current consumption lower than 150 nA. The first one has a positive temperature coefficient while the second one is temperature compensated. Silicon results from...
Portable and implantable device applications require low supply voltage reference circuits due to increasing trend for lower power requirements. Voltage references have been proposed for operation below 1 V for CMOS and a comprehensive analysis of the behavior of the different topologies is needed for ultra-low power designs, in order to select the right circuit topology for a given requirement. This...
