Abstract

In this paper a low power and low output ripple regulator is designed with teaching-learning-based optimization (TLBO) for radio frequency identification applications. In order to decrease the power consumption the voltage of regulator sub-blocks is supplied from elementary stages. In the proposed operational amplifier employed to the regulator, adaptive biasing is used and bandgap reference of the regulator is totally designed by MOSFET. To optimize the proposed regulator after modeling the regulator with the help of neural network, TLBO algorithm is used. The outputs of TLBO are output voltage, ripple value and power consumption. By using this algorithm the output voltage is 0.8 V with 2.78 mV ripple and \(115\,\upmu \hbox {W}\) power consumption. Also the quiescent current of this design is decreased to 290 nA. The chip area of the layout design in Cadence software is about \(0.00124\,\hbox {mm}^2\). The operation frequency of this circuit is 960 MHz and the simulation is done in \(0.18\,\upmu \hbox {m}\) CMOS technology.
