The invention relates to a front-end electronic circuit (10) for an electromagnetic radiation sensor, comprising: a charge-sensitive amplifier stage (100) having a first single-input operational transconductance amplifier (110) and a transistor (120) arranged in a first feedback path (101) of the first single-input operational transconductance amplifier (110); a signal shaper stage (200) having a second single-input operational transconductance amplifier (210) and an active feedback circuit (201) arranged in a second feedback path (201) of the second single-input operational transconductance amplifier (210). The front-end electronic circuit (10) also includes a control circuit (300) having a second transistor (310). The control circuit (300) is configured for providing a control signal (Vbias) to control the transistor (120) of the first feedback path (101) according to a gate-source voltage of the second transistor (310). 本发明涉及一种用于电磁辐射传感器的前端电子电路(10)，包括：电荷敏感放大器级(100)，具有第一单输入运算跨导放大器(110)和晶体管(120)，该晶体管布置在第一单输入运
