Pressure transducer working principle 

Pulse oximetry measurement section 

LED control signals 

The processor sends pulse width modulated signals, IRED intensity and RED intensity, which are 
converted to DC voltage and filtered. By switches either RED or IRED intensity is sent forward to 
amplifier in LED driving circuit. 

LED driving circuit 

Voltage difference which corresponds to LED current, is measured by the differential amplifier 
circuit and its output is sent back to the processor in 0 to 5 V level. There are feedback circuits from 
LED current measurement and LED intensity control. 

Measured signal preamplification 

Preamplifier is a current-to-voltage converter with gain selection.

 

Digitally controlled amplifier 

D/A converter is part of a digitally controlled amplifier after which there is another constant 
amplifier.
