Simulation Results

Mobile equipment such as organic-EL display, digital still camera and so on re-quire both positive and negative power supply voltage to obtain high quality. Single InductorMultiple-Output (SIMO) DC-DC converter can provide a pair of positive and negative outputvoltages with only one external inductor. This paper describes SIMO DC-DC Converter usingproposed current-mode control (CMC) circuit. The proposed CMC circuit realizes high responsespeed for the change of load current. Spectre simulations with 0.18m CMOS process parameterare performed to verify the validity of the proposed converter. The simulation results indicatethat the proposed converter has higher response time compared with conventional converter.

This paper deals with the modeling and simulation of low voltage power supply (LVPS) unit to the ACTIVE PHASED ARRAY RADAR, which is used for sensing different targets at a time. This RADAR system contains flat bank of small identical antennas and huge number of transmitting and receiving modules for electronic scanning. This radar antenna requires power in different levels for various electronic devices. The proposed design of LV power supply will have the ability to manage temperature variations with high efficiency under different loading condition. The closed loop control such as voltage mode control and current mode control are used to regulate the output voltage with high switching frequency of 400khz has been designed. Simulations are performed using MATLAB / SIMULINK software.
