A front-end electronic circuit (10) for an electromagnetic radiation sensor application includes a signal shaper circuit (1000) having an amplifier circuit (1100) and an active dynamic feedback circuit (1200), the active dynamic feedback circuit (1200) being disposed in a feedback path (1001) of the signal shaper circuit (1000). The active dynamic feedback circuit (1200) includes a first input transistor (100) disposed in a first current path (1201) of the active dynamic feedback circuit, and a second input transistor (200) disposed in a second current path (1202) of the active dynamic feedback circuit (1200). The first input transistor (100) has a control node that receives an output signal (Voutshape) of the signal shaper circuit (1000), and the second input transistor (200) has a control node that receives a reference signal (Vref). The active dynamic feedback circuit (1200) comprises a buffer circuit (300) arranged to decouple the first and second current paths (1201, 1202). 一种用于电磁辐射传感器应用的前端电子电路(10)包括具有放大
