A novel source–drain follower (SDF) has been designed and characterized as part of the effort to optimize the effective sensing node capacitance of the MAPS for the ALICE ITS upgrade. The standard source follower circuit, traditionally used for MAPS readout, compensates the input transistor gate-source Cf capacitance because of the follower action. In the SDF circuit both input transistor source and drain follow its gate, thus reducing the sensing node capacitance by removing the input

Monolithic active pixel sensors (MAPS) receive interest in tracking applications in high energy physics as they integrate sensor and readout electronics in one silicon die with potential for lower material budget and cost, and better performance. Source followers (SFs) are widely used for MAPS readout: they increase charge conversion gain 1/Ceffor decrease the effective sensing node capacitance Ceffbecause the follower action compensates part of the input capacitance. Charge conversion gain is critical for analog power consumption and therefore for material budget in tracking applications, and...
