    Ink jet printing has matured to a state where it can be used easily and precisely to print soluble electronic materials in order to produce complete circuits. Here we will show results of printed electronic components and a rectifier circuit intended be used in low-cost RFID tags. Commercial materials and a commercial research ink jet printer were used. Materials were deposited on pre-patterned aluminium electrodes. As the dielectric, poly-vinylphenol (PVPh) with poly-(melamine-co-formaldehyde) PMF cross linker was chosen. P3HT was used as the semiconductor, and finally PEDOT:PSS and ANP silver ink were used as top electrodes and wiring. Resulting capacitors and Schottky diodes were measured and an APLAC simulation model was constructed. There are trap states in forbidden gap of the semiconductor in the organic Schottky diode. Measurement result of frequency dependence of capacitance shows that different trap states induce different time constants. In the APLAC simulation, we used 8 diodes parallel which had different time constants to simulate the influence of the trap states. The results of the currentvoltage and capacitance-frequency simulations show that our model fits the measurement data well. We will use this model as functional component in our rectifier circuit simulation. The antenna circuit and load will be tuned according to simulation results. The measurement and simulation results for the whole circuit will be presented.
