description A paper dispenser having a proximity detector for dispensation of paper therefrom. The dispenser includes a housing having an inner chamber adapted to support a roll of paper. The housing also has a dispensing aperture. A motor is adapted to dispense paper from the roll through the dispensing aperture. The dispenser also includes a proximity detection circuit, which comprises an antenna, an oscillator circuit to charge the antenna, an operational amplifier operated as a unity gain follower which receives an antenna signal from the antenna, a detector circuit which detects changes in the antenna signal, and a comparator which actuates the motor in response to changes in the antenna signal.
