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 … ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with ...

Successful high-speed circuit designs need the right combination of grounding, power-supply bypassing, and decoupling. Modern op amps have much higher operating bandwidths than their predecessors ...

The circuit is based on a single AD8534 quad op amp chip. The first stage measures the voltage across the circuit under test in response to small current and amplifies it.

When the circuit is powered on, there is initially no photodiode current. The voltage at the positive input of the op-amp is pulled to VCC, and the op-amp powers the laser diode. This induces current ...

It resulted in the circuit in Figure 1. Figure 1 Using photocells instead of a voltage converter to help provide a true zero volage on the output of an op-amp buffer for a high-resolution ...
