• IHP Microelectronics - RF/Analog circuit design engineer

  2013 - maintenant Master Thesis: Power Amplifier Topology optimized for high Efficiency at Back-Off
  using a Single Transistor at L frequency band using GaN HEMT. IHP Microelectronics,
  Frankfurt Oder, Germany.
  In general, power amplifiers need for practical applications to have a high efficiency at Pout_max but also at Pout_backoff. The latter depends on the modulation used; however it remains a relevant aspect for most of all modulation schemes. For this, numerous topologies have been proposed and are used in practical realizations. Most of them use more than one (the main) transistor, for example to realize an ET or EER based amplifier. In all the design proposed earlier for obtaining high efficiency at back off the designers have used one main transistor for phase information signal and the other transistor for information modulated signal which results in high chip area, more power consumption and reduced efficiency.
  
  This leads to the design of hybrid mode power amplifier comprising ofclass F and class AB network. This amplifier was designed in order to get high efficiency and
  power added efficiency at back off which was attained quite successfully.

• ESYCOM Lab - Antenna designer

  2012 - maintenant Lab Session/internship: Design of Quadriband Antenna using 4Nec2 at ESYCOM lab.
  The goal of this project was to do a Quadriband antenna working in different band of frequency.
  - Main GSM bands: 900MHz, 1800MHz
  - Main low range wireless link bands: 2400MHz and 5900MHz.
  The main block, would be for the lowest frequency, and composed by a driven element the IFA, and the ILA soldered to ground. The distance between the two antennas would help to matches it.
  To adjust in all bands, the system must be matched for each of these frequencies, so the different branch of this antenna would be matched to their respective frequency. The antenna was designed and soldered on PCB.

• Ulm University - Circuit design engineer

  2012 - 2012 Minor Internship (Visiting student): Worked on Sub harmonic mixer and dynamic
  frequency divider at 94 GHz using .25umt SiGe HBT from IHP Microelectronics. Ulm
  University, Germany.
  Sub harmonic mixer was designed using Gilbert cell mixer and low pass filter.
  Dynamic frequency divider consists of gilbert cell mixer, TIA and filter.
