Description

We will present the development of an electronics board that will make the rapid characterization of multipixel silicon sensor arrays for fast timing possible. OPTIMA is optimized for multichannel readout, such that full information relative to the timing performance of shared charge between pixels is acquired. Each channel comprises a dual-stage amplifier design with a uniform response up to a frequency range of 8 GHz. A trans-impedance amplifier configuration using a SiGe transistor is used for both stages. The design features a passive daughterboard for versatile sensor replacement. Full characterization has been done in the lab achieving a total gain of more than 100. LGAD and 3D sensors have been tested in the test beam, and time resolutions of less than 50 ps have been obtained. Moreover, the board has been synchronized with the Timepix4 telescope. These preliminary results will be presented.
