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.
