1. Mimosa 22

2. Overview • Process 0.35 µm (AMS c35b4/opto) (3.3V ± 0.3V) • Matrix of 575 x 136 pixels with 18.4 µm pitch • 128 digital columns and 8 analog columns • Raw digital output without zero suppression • Main goals: • Characterize the new pitch • Make a design which is working with large matrices (2 cm x 2 cm) • Improve testability Mimosa 22 Frederic.Morel@IReS.in2p3.fr

3. Overview • 3 main types of pixels (2 structures with reset and 1 with self-bias diode) • different size of diodes (due to the new pitch) • Radtol and non radtol diodes • See A. Dorokhov presentation • Fully controlled by JTAG for configuration and testing • Including Bias and voltage references • See Mimosa 22 User Manuel • See G. Claus presentation Mimosa 22 Frederic.Morel@IReS.in2p3.fr

4. Functional view The Bias generator, Sequencer, Readout and JTAG controller are not represented • FRDO = 100 MHz • Discriminator frequency = 6.25 MHz • In pixel frequency = 100 MHz • Integration time = 92 µs Shift Row Reg 575bits Pixel array 575x136 Pixel sequencer + Buffer tree FRDO (16 CK) Two JTAG set test voltages emulated pixel outputs Dynamic & static 8 Analog outputs 128 Discriminators FRDO / 16 Disable discriminator Register Simple digital pattern generator for data transfer test purpose 81 81 81 81 81 81 81 81 81 81 81 81 81 81 81 81 FRDO Pads • The pixel was designed to work at 160 ns. Due to large capacitances of the output lines, 200 ns for reading one line is better. Mimosa 22 Frederic.Morel@IReS.in2p3.fr
