Electrical Engineering and Computer Science EECS373 - Design of Microprocessor-Based Systems Put Your Title Here Name1, Name2, Name3 {name1, name2, name3}@umich.edu Introduction: Write some title for intro • Plethora • Phone of Jack: mobile Literally a phone interfaces “plug-and-play” interface Some other title format Problem Description: Describe the problem in a few words • DC not possible to generate from headset • Direct rectification incurs significant power losses • Active rectification requires supply/gate drive voltages Active rectifier Proposed Solution: How did you solve the problem? Some title • Describe what you did. Add Pictures! Communication & Sensors • Hardware accelerated Soft-Modem on MCU • Manchester encoded digital communication • Building out the square-inch 8.82 kbps at 3.1x10-5 BER sensor ecosystem • Impact on Phone Battery: 200 mW Conclusion With the basics of powering external devices and communicating with them now in place, it will soon be possible to plug a small circuit board into almost any existing mobile phone, power an external sensor (e.g. EKG, PulseOx, etc.), bias it with a voltage, read its analog output back, perform some sophisticated filtering, and present an instant result. In short, a parasitically-powered analog expansion interface for the mobile phone will enable many new applications that are either impossible or infeasible with today’s technology. 1 You can add your link down here to your project
