METHOD AND SYSTEM FOR CORRECTING NON-LINEAR RESPONSE IN AMPLIFIERS |
摘要 |
A method for extending the linear range of operation of an amplifier includes monitoring a transistor voltage of a transistor of an amplifier. The transistor is coupled to a variable current source applying a bias current to the transistor. The method continues by monitoring an output voltage of the amplifier and by determining whether the transistor voltage is within a predetermined range of the output voltage. If the transistor voltage is not within a predetermined range of the output voltage, the method continues by decreasing the bias current applied to the transistor. If the transistor voltage is within a predetermined range of the output voltage and if the bias current has not previously been decreased, the method continues by increasing the bias current applied to the transistor. |
