  1. Oscillator/Demodulator to Fit on Flexible PCB Senior Design Team 181 www.transtekinc.com

  2. (Re)Introduction • Team: • Ryan Williams (EE) • Jonathan Wolff (EE) • Damon Soto (EE) • Jason Meyer (EE) • Advisor: Helena Silva (ECE) • Trans-Tek Contacts: • Mark Bennett • Jeffrey Gladu

  3. Outline • LVDT Background • Current Oscillator/Demodulator Model • Design Alternatives – Oscillator • Design Alternatives – Demodulator • Final Design • Goals • Progress • Timeline • Budget

  4. LVDTs • Consists of a 3-part transformer • Secondary coils wired in subtractive configuration • Position of core determines output voltage • Linear relationship between core position and output voltage http://upload.wikimedia.org/wikipedia/commons/0/07/Lvdt_how.gif
