Fig. 1 shows a basic test circuit I constructed. When the LED is turned on reverse current flow through the photodiode from cathode to anode to the base of Q1. The current is amplified and use to light up a LED. This is an ON/OFF circuit useless for measuring light intensity. ...

The Conventional Op Amp The conventional op amp consists of a high input-impedance differential stage followed by additional gain stages, the last of which is a low output-impedance stage. As shown in the circuit model of Figure 25-2a, the op amp transfer characteristic is Sign in to downloa...
or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, no...
Ideally, a true rail-to-rail input op amp has an input common-mode range that includes both supply rails, and an output range which does likewise. This makes for some interesting tradeoffs and compromises in the circuit design of the op amp. In many cases, an op amp may be fully ...

With high bandwidth and pico-Ampere input bias current, the TSV781 and the TSV782 are also well suited for photodiode signal conditioning in a transimpedance amplifier circuit. This application is useful in high performance UV sensors, smoke detectors or particle sensors. Automotive grade qualified ...
However, together with the diode parasitic capacitance, the op amp input capacitances and the PCB stray capacitance, this feedback network creates a pole that makes the circuit oscillate. Using a small (few pF) capacitor in parallel with the feedback resistor is mandatory to stabilize the ...
