The circuit’s flexibility permits it to receive multiple modulation methods. A low noise, high frequency preamplifier performs a current-to-voltage conversion while rejecting low frequency ambient interference with an AC coupling loop. Two separate high impedance filter buffer inputs are provided so that off-chip filtering can be tailored for specific modulation schemes. The filter buffers drive separate differential gain stages that end in comparators with internal hysteresis.
