Abstract: A charge sensor circuitry comprises: a detector element configured to generate a charge signal at an internal node; wherein the charge sensor circuitry comprises a first transistor comprising a gate for receiving a first control signal and at least one second transistor comprising a first gate connected to the internal node and a second gate for receiving a second control signal; wherein the charge sensor circuitry is configured to, in a first mode, output a first output signal through the first transistor; wherein the charge sensor circuitry is configured to, in a second mode, reset the internal node through the first transistor and output a second output signal through the at least one second transistor.

Abstract: A charge sensor element includes a charge collecting detector configured to generate an intensity signal indicative of an amount of charge at an internal charge sensor element node, an amplifier transistor that is electrically connected to the internal charge sensor element node and configured to amplify the intensity signal, and a reset transistor that is electrically connected to the internal charge sensor element node and configured to reset the intensity signal. The amplifier transistor or the reset transistor includes a front gate and a back gate that are configured to control the amplifier transistor or the reset transistor.
