The circuit provided is a VU meter driver with bipolar peak detection. This clever design features a peak indicator LED that will illuminate once the peak level reaches 3dB over 0VU (the same peak ...

This technique usually works well unless your design requires operation higher than a ... frequency response and peak-to-peak input-voltage range of the peak detector (Reference 1). The circuit in ...

The following circuit improves upon a simple peak detector by using a high frequency op-amp and feedback circuitry. The result is better accuracy and more sensitivity at the input. To view the ...

Figure 1 demonstrates a one-way switched-capacitor gain stage circuit, performing a voltage gain of AO = ­C1/C2 only during the decreasing trail of the input signal Vi (with VJ... After the reset ...

The diode bias current is created by a transistor-based peak detector circuit driven off the main audio signal. But don’t just take our word for it, watch the video after the break.
