Abstract :
An integrated DC-DC converter with two passive external components was designed and fabricated in an advanced, short-channel (Leff <0.2 μm, Vdd<2 V) CMOS technology. This design was undertaken to examine the feasibility of implementing an inductive buck converter with passive components small enough to fit entirely within a packaged chip. High switching frequencies (>10 MHz) were used to minimize the size of external components, and novel circuits were used to reduce the stress on the short channel devices. Measured efficiencies for a 3.3 V to 1.65 V converter were approximately 75% for output currents from 15 to 40 mA
