ABSTRACT:
A comparator compares the voltage of an envelope signal by applying envelope detection to a signal amplitude-modulated by a digital signal encoded by a Manchester code with the terminal voltage of a capacitor constituting a filter for converting the output current of a charge pump into a voltage. The charge pump charges/discharges the capacitor by discharging or charging current, according to the result of the comparison.
