Abstract
A type-A demodulator comprising a first rectifier configured to rectify a radio frequency (RF) signal received through an antenna and output a first voltage, a second rectifier configured to rectify the voltage of the RF signal received through the antenna and output a second voltage having a different voltage level than the first voltage, and a pause data detector configured to compare the first voltage with the second voltage and detect received pause data.
