Abstract

In this work, a step down DC/DC converter aimed at reducing the supply voltage in implantable medical devices is presented. The circuit was designed and fabricated in a 0.6 μm technology. The DC/DC converter was tested for a wide range of input voltages between 1.9V and 5V, output voltages between 200mV and 1.5V, and different load currents between 50μA and 200μA. In all cases the output voltage was regulated with less than 3% error and 5% ripple. The simulated efficiency varied between 60% and 75%, but the measured efficiency was 40%.
