Fast peak detector requires special amplifier features. The output stage must have high slew rate to keep up with the intermediate stages of the amplifier. This condition causes either a long overload or DC accuracy errors. The amplifier must deliver large currents into the capacitive load of the detector to maintain a high slew rate [...]

A simple half-wave peak detector using a single transistor is very compact and low cost, but if the application require precise detection for signal under 100mV then that circuit become useless. Here you can use more precise half-wave peak detector circuit using only a single op-amp with few passive components. Look at the circuit’s schematic [...]

A fast peak detector similar but faster than previous peak detector, can be implemented using open loop configuration. Here is the schematic diagram of the circuit: In this  design, D1 is the detector diode and D2 is a level shifting or compensating diode. A load resistor RL is connected to – 5V and [...]

Using only a single transistor and few passive components, you can build a fairly sensitive peak detector. circuit This peak detector circuit is suitable for audio application, since the average sum of positive and negative cycle of audio signal has equal value. You can find a peak signal although you only detect the peak of [...]

Implementing peak-detector circuits is very easy with the CA3130, as shown in schematic diagram of this circuit. The figure below shows the schematic diagram of the peak detector circuit. The upper section is peak-positive and the lower section is peak-negative circuit. Please note that with large-signal inputs, the bandwidth of the peak-negative circuit [...]

This circuit detect the amplitude of audio signal, suitable for audio level detection that demand for high precision. Amplitude detection or signal envelope detection is usually implemented using a peak detector. An ideal amplitude detector give continuous level at any time because the amplitude of a sine signal (every signal can be seen as sine [...]
