摘要：

An integrated de-de converter with two passive external components was designed and fabricated in an advanced, short-channel (L(eff) < 0.2 mu m, V-dd < 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.
