Abstract: Wireless battery-powered portable electronic devices give opportunity to the people to have faster communication with each other. The increased functionality of mobile phones enables large data packages to be transmitted in the real time. Decreasing of power losses in the electronic building blocks of the transmitter will increase the battery life and system run-time. Power amplifier (PA) is the most energy consuming block. In this paper are considered various power supply circuit architectures suitable for portable electronic devices. Buck dc-dc converter using Pulse-Width Modulation (PWM) designed on CMOS 0.35 μm process is presented. The power losses in the output switching transistors, filter inductor and filter capacitor and evaluated. The efficiency performance of the converter as function of switching frequency fs and inductor current ripple ΔiL is investigated.
