  • Base station for a contactless interrogation system comprising a phase locked and voltage controlled oscillator
    Patent number: 6272320
    Abstract: A base station (13) for a contactless interrogation system includes an oscillating device (23) supplying a control signal having a frequency which is adjustable via adjusting circuits (21, 22), a circuits (24) for controlling an antenna connected to the base station (13) for transmitting information, decoding circuits (25, 26, 27) for decoding the information picked up by the antenna. The oscillating device (23) is a voltage controlled oscillator which is phase locked by the adjusting circuits (21, 22), so that the control signal frequency is determined by the base station (13) and is adapted to the antenna. The sensitivity of a contactless interrogation system comprising the base station (13) of the present invention is improved, its structure is simpler and its different components can be integrated in a same chip.
