This high input impedance circuit is suggested by Motorola's 1993 Linear Interface ICs. The power supply must be symmetrical. The circuit has a differential input.
We found this circuit in an old Argentine publication. The transistor can be replaced by a more...
The sensor of this circuit is a large surface diode. We believe that a small solar cell can also...
