Akif Alvi Arnab

I am a Bangladeshi International student at the TU Hamburg studying M.Sc. in Microelectronics and Microsystems (MEMS).My Bachelor Studieswere completed in Bangladesh in Electrical and Electronics       Engineering (EEE). At the TUHH, I have completed electronics-based theory and practical courses such as Analog and Digital Circuit Design, Mixed-Signal Circuit Design, Electronic Device and Circuits and Fundamentals of IC Design where I learned about designing electronic circuits, simulation of mixed-signal designs, implementing them using simulation tools like Cadence, LTspice and MATLAB-Simulink, lay-outing of electronic circuits using Cadence Virtuoso. I completed my Master Project on designing a Low-Power Low-Dropout Regulator (LDO) in Cadence Virtuoso in X-fab 180nm XH018 Technology for an Energy Management Unit (EMU) where the goal was to design a circuitry that provides a constant 1.8V voltage to the different parts of the EMU with a very low quiescent current (3.2µA in my case). Defining the LDO specifications from the energy management unit was an important part of the project work. At the moment I’m working on Master Thesis on ‘Investigation of low-noise pre-amplifiers for magneto-electric sensors’ where I’m analyzing the noise performances of common-source, common-gate, common-drain, common-source cascode amplifiers, conventional differential amplifiers, bulk-driven differential amplifiers, two-stage operational amplifiers and folded-cascode amplifier in Cadence Virtuoso in X-fab 180nm XH018 technology and the goal is to achieve an input referred noise less than 1µV/sqrt(Hz) for the sensor. The best performed amplifier is then further developed and PVT (Process Voltage Temperature), Monte Carlo simulation and layout of the op-amp has to be designed.  In the Analog Circuit Design course, I did a complete layout of a 2 stage Operational Amplifier which I designed with gm/ID methodology in AMS 350nm CMOS technology. In the Mixed Signal Circuit Design course, I designed a bit SAR-ADC (Successive Approximation Register Analog to Digital Converter) in MATLAB-Simulink and tested the non-idealities such as DNL (Differential Non-Linearity), INL (Integral Non-Linearity) and ENOB (Effective Number of Bits). In the Digital Circuit Design course, I designed a 16-bit Microprocessor using Verilog and synthesized it using 350nm CMOS technology
