The design and the preliminary measurements of a prototype 10 bit pipeline ADC based on 1.5-bit per stage architecture, developed for the luminosity detector at International Linear Collider (ILC) are presented. The ADC is designed in two versions, with and without a sample-and-hold circuit (S/H) at the input. The prototypes are fabricated in 0.35 μm CMOS technology. A dedicated test setup with a fast FPGA based data acquisition system (DAQ) is developed for the ADC testing. The measurements of static (INL, DNL) and dynamic parameters are performed to understand and quantify the circuit performance. The integral (INL) and differential (DNL) nonlinearity are below 1 LSB and 0.5 LSB respectively. The dynamic measurements show signal to noise (SNHR) ratio of about 58 dB for sampling frequency up to 25 MHz.
The azimuthal anisotropies of particle yields observed in relativistic heavy-ion collisions have been traditionally considered as a strong evidence of the formation of a de-confined quark-gluon plasma produced in thes...
