The concept of active pixel sensor based on depleted P-channel FET (DEPFET) has been developed to cope with the emerging requirements of low noise and speed. The DEPFET detector/amplifier [1], thanks to an intrinsic low anode capacitance, can provide excellent energy resolution and fast readout at t
