AB  - A fully digital photoplethysmographic (PPG) sensor and actuator has been 
      developed. The sensing circuit uses one Light Emitting Diode (LED) for emitting 
      light into human tissue and one LED for detecting the reflectance light from 
      human tissue. A Field Programmable Gate Array (FPGA) is used to control the LEDs 
      and determine the PPG and Blood Oxygen Saturation (S(p)O(2)). The configurations 
      with two LEDs and four LEDs are developed for measuring PPG signal and Blood 
      Oxygen Saturation (S(p)O(2)). N-LEDs configuration is proposed for multichannel 
      S(p)O(2) measurements. The approach resulted in better spectral sensitivity, 
      increased and adjustable resolution, reduced noise, small size, low cost and low 
      power consumption.
