“I jammed with Steve Morse once, and liked his 5150 amp, so they sent me two. They sounded great for about 10 seconds, then they were fried!” ...

The design of this circuit is to solve the problems during ECG signal collection, such as noise interference and circuit complexity. To ensure the volume, signal accuracy, and economy of the circuit, ...

Want to repurpose an operational amplifier from a previous project or an old parts collection? You can construct a specialized op-amp tester quickly.

In the previous issue, we examined the behavior of a one-level limiting circuit. Now, we will analyze the two-level limiting circuit.

This circuit is an especially simple op-amp application, and is a typical one for a sensor interface where a DC voltage needs to be brought into range of a microcontroller.

Engineers often use SPICE simulations for operational amplifiers to look at the stability of a proposed circuit. SPICE simulations are particularly frequent for high-speed amplifier applications where ...

This PWM amplifier circuit has a pretty good response at higher frequencies while eliminating the problem of shoot-through.

The op-amp circuit in question. He starts with the current source, a simple circuit of two diodes, a resistor, and a transistor that sets the bias for the two-transistor differential amplifier.
