| titleOfInvention | Power control device wherein a bias voltage in level detection is given a constant difference from a detected voltage |
| abstract | In a level detector (17), a bias voltage is developed by a bias current to have a substantially constant difference irrespective of a temperature variation from a detected voltage produced by detecting a device output signal for use in TDM modulation. A control signal generator (19) calculates a substantially temperature independent difference digital value by subtracting from a first digital value of the detected voltage and a second digital value of the bias voltage to produce an attenuation control analog level used in controlling a variable attenuator (11) which deals with a device input signal to produce an attenuator output signal with a desired value for use as the device output signal. Preferably, the detected and the bias voltages are amplified by a variable gain amplifier (35) controlled by a processor output signal. |
