摘要：

This paper presents a concept for rectifying low ambient radiation sources to supply autonomous measurement systems like microsystems. Among an analytic computation and nonlinear simulation of the rectifier circuit with ADS (Advanced Design System), the circuit was built and the efficiency factor of the RF-Harvesting system was measured A radiation source with the power of 1 mu Watt (-30dBm) and an impedance of 50 Ohm at 300 MHz was used. By well matching of the impedance and a resonance circuit transformation with a high quality factor in front of a Schottky-Diode a passive charge pump with the factor of 25 was realized.
