摘要：
A differential amplifier can include input transistors for receiving a differential input signal and an inductor connected to the input transistors. The inductor can protect a voltage supply from radio frequency in the differential input signal. The accuracy of this differential amplifier can be significantly improved by including a bias network. This bias network advantageously allows a bias current in the input transistors to be set independently of a voltage drop across the inductor.
