Modern operational amplifiers (op amps) and instrumentation amplifiers (in amps) provide great benefits to the designer, when compared with discrete semiconductors. But all too often, some very basic ...

A straightforward, fast, temperature-compensated, calibration-free, and accurate variation of the classic squaring circuit.

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

Crazy Tube Circuits has done it again, and by again we mean it has released a fully featured amp-style overdrive pedal that pairs a classic amp drive voicing with a classic pedal – on this occasion a ...
