Zusammenfassung:A transconductor circuitry (10) with adaptive biasing comprises a first input terminal (ElOa) to apply a first input signal (inp), and a second input terminal (ElOb) to apply a second input signal (inn). A control circuit (200) is configured to control a first controllable current source (110) in a first current path (101) and a second controllable current source (120) in a second current path (102) in response to at least one of a first potential of a first node (Nl) of the first current path (101) and a second potential of a second node (N2) of the second current path (102). The first node (Nl) is located between a first transistor (150) and the first controllable current source (110), and the second node (N2) is located between a second transistor (160) and the second controllable current source (120). 具有自适应偏置的跨导器电路(10)包括用于施加第一输入信号(inp)的第一输入端子(E1Oa)和用于施加第二输入信号(inn)的第二输入端子(E1Ob)。控制电路(200)配置为响应于第一电流路径(101)的第一节点(N1)的第一电位和第二电流路径(102)的第二节点(N2)的第二电位中的至少一者来控制第一电流路径(101)中的第一可控电流源(110)和第二电流路径(102)中的第二可控电流源(120)。第一节
