Project Results
Project Goals

• The following depicts the accuracy between the
  researched data and
• PSPICE model data of the organic diode.
• The following depicts the output comparison of
  the silicon and organic
• implementation of the charge pump.
• Silicon Charge Pump

• Research organic components and the charge pumps
  importance to
• an RFID tag
• Model organic components
• Design a practical charge pump schematic
• Simulate charge pump schematic using modeled
  organic components

Project Overview

• Superior Organics will design a charge pump using
  organic components.
• This charge pump will accept a low RF input
  between
• 128 to 135 kHz and output a DC voltage of 5
  V.
• Block Diagram Overview
• Voltage Regulator lowers the input voltage to 1
  V.
• Charge Pump is designed in 5 stages.
• Input voltage accepts a minimum of 1 V
• Each stage increases the voltage approximately
• by 1 V
• Output voltage is approximately 5 VDC
• We first tested the charge pump using Silicon
  diodes.
• Next we tested the design using organic
  diodes.

Project Conclusions/Outcomes

• Superior Organics produced a charge pump design
  in which the input
• RF signal is applied into a voltage regulator
  that converts and clips the
• DC signal to 1 V.
• However, our working design is limited to certain
  input DC voltages to the
• charge pump. With more designing and
  calculating, we will be able to
• expand the range of voltages.
• By comparison, we experimentally observed that
  the organic
• components obtain less gain per stage and
  need a slightly higher rise
• time to produce the same results as inorganic
  components. However,
• for our application, this is inconsequential.
  
• Once we improve our design, we will move towards
  the fabrication of our
• design with the assistance of Dr. Gnade.
