Abstract
A 13.56 MHz CMOS ring oscillator for DC/DC converter is demonstrated where measured performances make it suitable for wireless power transfer receiver system. The proposed structure employs a supply-regulated ring oscillator with a temperature compensated current bias circuit, which minimizes the frequency sensitivity to supply and temperature variations. Fabricated in a 0.11 μm 1P5M CMOS process, the developed oscillator as a switching frequency generator of DC/DC converter dissipates maximum 6.8 mW while exhibiting ±0.88 % frequency error against temperature variation of 0-125 °C.
