Keywords
  • An Amplitude Shift Keying (Ask) Demodulator Is Presented Which Is Suitable For Implantable Electroni
  • The Demodulator Has Been Tested With Carrier Frequencies In The Range 1-15 Mhz
  • Covering Most Commonly Used Frequencies
  • Data Rates Up To Several 100Kbit/S Are Supported
  • Suitable For Complex Implants Such As Stimulating Electrode Arrays Or Visual Implants
  • The Circuit Is Compatible With Modulation Depths In The Range 10-100%
  • The Low End Of The Range Permits Data Transmission Without Significant Reduction In Power Transfer
  • Or The Use Of Transmitter Designs With Limited Modulation Capability
  • The Power Consumption Is 60 μW From A 3 V Supply
  • The Circuit Has Been Implemented In A Standard Cmos Process
