dc.description.abstractSeveral architectures are studied and a boost/buck power supply is proposed as to achieve superior efficiency. A boost and buck, dual mode converter core and drivers is implemented in a 180 nm cmos technology node and running at 220 MHz. Zero Voltage Switching and Width Switching is implemented to increase efficiency. The feedback control of the converter is modeled in Verilog-AMS as a voltage mode feedback with a PID filter. An efficiency of up to 78 % is obtained for a 2.4 V input, and 60 % with a 3.3 V input. This is not a superior efficiency, but higher than an ideal linear regulator. Seen in relation to that it is fully integrated, its switching frequency, and that neither the width switching scheme nor the zero voltage switching is fully tweaked, a further development of the proposed topology seems to be a possible solution of the realization of a stable integrated power supply with superior efficiency and low noise.nb_NO
