Abstract

A contactless communication device includes a receiver unit having differential input terminals for connecting to an antenna. The receiver unit is coupled to a transmitting device and receives an RF signal transmitted by the transmitting device. A first comparator is adapted to generate a first comparator output signal indicative of a relationship between a voltage at a positive input terminal of the receiver unit and a first reference voltage. A second comparator is adapted to generate a second comparator output signal indicative of a relationship between a voltage at a negative input terminal of the receiver unit and a second reference voltage. A first voltage regulation circuit is adapted to regulate the voltage at the positive input terminal in response to the first comparator output signal. A second voltage regulation circuit is adapted to regulate the voltage at the negative input terminal in response to the second comparator output signal.
