BIAS ARRANGEMENT AND APPARATUS

摘要

A biasing arrangement for an electronic apparatus having an input device is disclosed. The biasing arrangement comprises a bias voltage generator arranged to provide a bias voltage; a bias resistor connected between the bias voltage generator and the input device; and a reference voltage point of the input device, wherein a voltage of the reference voltage point of the input device is provided to the bias voltage generator for controlling the bias voltage in relation to the voltage of the reference voltage point of the input device. An electronic apparatus is also disclosed.
