This paper deals with the design and implementation of transmitter and receiver modules for pulse oximeter system. First, the fundamentals of noninvasive method for monitoring the oxygen saturation are briefly described. Next, two proposed modules and their monolithic implementations are presented and discussed. These sections describe the integrated transmitter and receiver circuits intended to work with transmitting and receiving diodes respectively. Several important simulation results are shown, including analysis proving proper cooperation between designed modules. Finally, brief summary has been made at the end of the article, describing future development of proposed solutions.
