Hi everyone,

I am a hardware design engineer, with 5+ years of experience in the field, who take freelance jobs on-demand. You can contact me and ask for information regarding any of your hardware design & development job. Please do not hesitate to contact me even if your project scope / design requirement is relatively small. If you have a design requirement which is not among the experienced areas listed below, I will charge you fairly low price.

  • 5+ years of professional experience in Hardware Design & Development
  • Experienced in schematic, board design, simulation, prototyping, PCB layout, component selection, debugging and functional verification
  • Experienced in
    • Mixed signal circuits:
      • High speed ADC/DAC designs having deterministic latency with one of the latest interface technologies, i.e. JESD204x
      • FMC board designs complaint with the VITA 57.1 mezzanine board standard
      • Power and digital signal distribution boards
    • Digital circuits:
      • FPGA board designs (I have only worked with Xilinx FPGAs, in case you desire an Altera FPGA design, I will charge you half of the price) complaint with the VITA 57.1 carrier board standard
      • JESD204x
      • 1Gb/10Gb Ethernet
      • RS232/RS422/RS485
      • USB2.0/USB3.0
      • SD Card
      • HDMI/Display Port
      • DDR3/DDR4
      • I2C/SPI/UART
    • Analog circuits:
      • Ultra-low noise, ultra-high gain transimpedance amplifier (TIA) designs for sensing applications (one of the previous TIA circuits has 130dB gain with 3-dB bandwidth of 100MHz, which is designed for fiber optic distributed acoustic sensing application)
      • High speed, high gain, low noise amplifier designs.
      • Analog filter designs using discrete components (You can see the S21 parameter of one of the previous filter designs, i.e. 13th order Chebyshev low-pass filter for with 3-db cutoff at 100MHz, which is used before ADC input as an anti-aliasing filter)
      • Circuits for optic devices such as AOM Driver, Optic Switch Controller, Laser Diode Driver
    • RF circuits:
      • RF amplifier circuits (including, but not limited to GaN amplifiers)
      • Low phase noise signal synthesizer circuits for downconverter applications and signal generators
  • Experience in a lab environment using oscilloscopes, spectrum analyzers, signal generators, optical power meters, fiber optic splicing machine, fiber scopes, optical spectrum analyzer
  • Expertise in PCB CAD tools including to Eagle, Altium
  • Expertise in simulation programs including LTSpice, AWR

Hello Canberk, Do you have experience in PCB layout, simulation of power electronic designs ? We are working on a solar inverter and need some support. Thanks.
