Dear Valued Employer, My name is Martin Botsov and I am an engineering physicist with extensive experience in the field of circuit design, circuit prototyping and PCB design. As I understand from the project description you are looking for an electronics engineer capable of designing an instrumentation circuit (a. k. a. signal conditioning or analog front-end) for low amplitude signals such as EEG, VLF or human body electrical signals. So, without further ado here's how the workflow would look like, if you happen to choose me as a partner for your project: 1. Initial discussion 2. Research 3. Proposal for solution 4. Block diagram of proposed solution 5. Schematic drafts based on proposed solution 6. Component library creation 6.1 Schematic symbol library creation 6.2 Footprint library creation 7. Schematic drawings 8. Review of schematic drawings 9. Layout design 9.1 Components placement and arrangement 9.2 Components routing 9.3 Review of final layout design 10. Design rule check 11. Final check, verification and validation 12. Production files (GERBER, NC DRILL, ASM, PICK & PLACE, STEP, BOM, SCH, 2D mechanical) Your project will be carried out on Altium Designer. Don't hesitate to contact me with questions regarding any details around your project. You could also check out my profile on Freelancer and LinkedIn for more details around my professional experience. I am looking forward to hearing from you soon. Thank you for you time. Kind Regards Martin Botsov

Hello, What resolution are you trying to achieve and what SNR are you attempting to get? Will you also be requiring the data acquisition front end as well? I use LTSpice for simulation and Eagle 6.5 for schematic and layout. Best regards, Stuart Borden

Hello, I am a certified EE engineer with more than 6 years of experience designing building and testing electronic devices. I work as a r&d engineer in a lab, and in my spare time I freelance. Most of my experience is in analog sensors and circuits. What exactly is your project? Do you have the eeg sensors and just need amplification or do you want the whole system? What kind of pressure do we need to amplify? Do you have an actuator in mind? Please contact me for further questions. Depending on what you want, the bid is negotiable. If you have any questions please contact me. Thank you.
