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.

WORK EXPERIENCE

• 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. 13^th 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

Best Regards,
Canberk

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.
