Abstract
A front-end electronic circuitry for an electromagnetic radiation sensor application includes a signal shaper circuit with an amplifier circuit and an active dynamic feedback circuit, the active dynamic feedback circuit being arranged in a feedback path of the signal shaper circuit. The active dynamic feedback circuit includes a first input transistor being arranged in a first current path of the active dynamic feedback circuit, and a second input transistor being arranged in a second current path of the active dynamic feedback circuit. The first input transistor has a control node to receive an output signal of the signal shaper circuit, and the second input transistor has a control node to receive a reference signal. The active dynamic feedback circuit includes a buffer circuit being arranged to decouple the first and second current path.
