ESR 02: Siddharth Bhat

Host Institution: 
Design of microelectronics circuits for low noise depleted CCPD and monolithic pixel CMOS sensor
Bachelors in electronics and communication engineering; Masters in VLSI design
Research Interests: 
  • Microelectronics
  • Circuit design for pixel detectors
  • IC characterization

My educational background is in the field of electronics.

I have obtained a bachelor in electronics and communication engineering and in 2016 I specialized in the field of VLSI design for my master from the SRM University in India.  My master thesis was on “Design of low voltage CMOS OTA using bulk driven technique”.

I started my research at Centre of Particle Physics Marseille (CPPM) already in August 2016 and I joined the STREAM ITN as ESR2 in February 2017.

Research at STREAM: 

I collaborate in the STREAM Work Package 2. This work package aims to evaluate potential of advanced HV and imaging CMOS processes against end-user specification for industrial application and particle physics.

My research focuses on analog/digital designs for monolithic and hybrid pixel detectors. The objective is to contribute to the next generation of sensors with suitable electronic simulations and designs.

The sensor prototypes produced in STREAM will be studied for charge collection, their influence of the electronics on the sensing part of the integrated technology and their behavior versus radiation. The project also involves IC characterization of HV/HR CMOS sensors.



Host Institution and Secondment Topic 

Expected secondment period

CERN (Geneva, CH), Involvement in irradiation

4 weeks in August 2017

CERN (Geneva, CH), Common submission work

 8 weeks in Oct-Nov 2017

CERN (Geneva, CH),  Involvement in the sensors design

2-3 weeks during 2018


Being an Early Stage Researcher of the STREAM ITN has given me the opportunity to work with some of the most acknowledged research teams, to attend and present my work to various workshops and conferences in the fields of electronics.

My PhD work and research will help in the development of TowerJazz, LFoundry, AMS technologies for the High luminosity LHC and promote the study of the technologies under the harsh radiation environment.

All these elements will help me to pursue a career in electronics.
