Fixed Price: Not Sure   |  Posted: Jun 15, 2015  |  Ends: 8d, 2h  |   8 Proposals
I am looking for someone to do PCB layout for a startup company. The board should contain eight transimpedance amplifiers, that can operate with high gain (1e8), high bandwidth (2e5 Hz acceptable, but prefer going up to 1e6 Hz), with low noise. These amplifiers would be used for applying a fixed voltage, and measuring small currents (less than 10 nA). To get an idea, a similar, acceptable layout can be found at:   [obscured]  /datasheets/1599345.pdf (though this board is for 1 amplifier, and not 8. Specifically looking for a board configured in transimpedance configuration, measuring current and applying a fixed voltage). Also, there are likely to be better opAmp packages that can be mutually agreed upon. These circuits are for high precision applications, so low leakage currents, low voltage drift, and low noise are all required. If possible, would also like to keep the size of the board to that of an Arduino header. If this is not possible, two boards of the Arduino size w...
