Optical systems have many unique attributes that make them useful for range detection and communications, but often the optical signal needs to be converted to an electrical signal as part of the ...

Fig 1. Shown is a basic TIA circuit used in dual-supply systems. Fig 2. Figure 1’s TIA circuit was modified for a single supply. Fig 3. Here, the TIA circuit in Figure 2 places a photodiode directly ...

In Case Study: Medical Laser System; Part 1: Stabilizing a Laser Feedback Control Loop, the nonlinear flashlamp in the laser control loop had a parabolic transfer function which was gain-compensated ...

Follow these seven steps to successfully select a photodiode sensor and design an analog front end for a range of applications such as optical communications and light-based measurements. The energy ...

In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

How to avoid amplifier output driver saturation when using very low bias current amplifiers with high source impedance sensors, write Jon Munson and Kevin Scott When taking sensor measurements, the ...
