pA level transimpedance amplifier

Overview:
- TIA cross-blocking weak current measurement module;IV conversion preamplifier,pA-nA-mA for silicon photodetection;
- Ultra-high precision current measurement module,the range: 10pA to 2mA (limit parameters);suitable for rapid development of personal projects;principle verification; are measured by 6 and a half instruments,Tektronix multimeters (DMM4050) 2363A).
- Using a typical transimpedance IV circuit connection,the current technology can achieve the highest level of current measurement accuracy.
- Main chip bias current as low as 1pA,rail-to-rail op amp,high accuracy.Input voltage only positive voltage can be (do not need negative voltage).
- "Positive and negative current input" version:The meaning of the input current can be positive or negative.Otherwise it can only be entered according to the specified current direction.
- Although the principle of analog circuits is very simple,but no problem is difficult to make.
- The circuit after many improvements,measured available and excellent performance.
- The formula of output voltage Vout and input current I is:Vout = VCC/2 ± I * R;
