This photo amplifier design is based on the transimpedance amplifier from Hobbs book (Building Electro-Optical Systems, Making It All Work, Second Edition, Ch. 18 - Front ends) and Brian Patton's design for a photo amplifier with single-sided outputs. The bandwidth of this board is 20 kHz, but can be increased well beyond that by changing the RC constants in the feedback of the opamps. == TODO == * Smaller power connector * Label +, GND, - on the power connector == Schematics == * Schematics - [[File:Amplifier schematics.pdf\|download]] == BOM and assembly == * BOM and assembly - [[File:Amplifier BOM and assembly.pdf\|download]] == Noise, gain, phase caclulations == Mike calculated what is the noise of the board at the photocurrents we are measuring (~2 uA). They are well below the shot noise limit within the bandwidth. * Mathematica notebook - [[File:TransimpedanceAmpResponse.zip\|download]] * TI application report - [[File:Sboa122.pdf\|download]] == Eagle design == * Board design, Eagle 6.6.0 - [[File:Differential photocurrent amplifier.zip\|download]]
