Abstract

A charge sensor circuitry (110; 210; 310; 410) comprises: a detector element (112; 212; 312; 412) configured to generate a charge signal at an internal node (114; 214; 314; 414); wherein the charge sensor circuitry comprises a first transistor (118; 218; 318; 418) comprising a gate (122; 222; 322; 422) for receiving a first control signal and at least one second transistor (124, 126; 224, 226; 324; 424) comprising a first gate (128; 228; 328; 428) connected to the internal node and a second gate (130; 230; 330; 430) 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.
