(ZH) 一种控制电路、偏置电路及控制方法
Abstract:
(EN) Provided are a control circuit (45), a bias circuit, and a control method, wherein the control circuit is applied to the bias circuit. The bias circuit comprises a first transistor (41) and a second transistor (42). A gate of the first transistor (41) is connected to a gate of the second transistor (42). The first transistor (41) and the second transistor (42) are configured to amplify an input reference DC current of the bias circuit to obtain a bias DC current. The control circuit comprises: a detection circuit, configured to compare a first DC voltage with a second DC voltage to obtain a comparison result; the first DC voltage being a drain DC voltage of the first transistor (41); and the second DC voltage being a drain DC voltage of the second transistor (42); and a regulation circuit, configured to regulate the first DC voltage and the second DC voltage using the comparison result, such that the drain DC voltage of the first transistor (41) operating in the bias circuit is the same as that of the second transistor (42) operating in the bias circuit.
