Peak detector circuit using opamp. The big advantage of this circuit is represented by the small threshold the operation of a peak detector can be illustrated using a simple diode and capacitor, as shown in that can rectify the amplitude signal, detect the peak signal and change the dc level of waveforms. The pulsatile waveform on the ppg usually occurs much later than the corresponding qrs complex in the ecg). Peak detectors are often used to capture transient events that may otherwise remain undetected, but can they can also be used to capture the instantaneous voltage peaks from a power amp, and the idealised case for the output waveform is shown next. A peak detector circuit is used to determine the maximum (peak) value of an input signal.
Additional code is implemented which accounts for delay present on signals not directly measuring the heart beat (e.g. Hence i decided a peak detector might be a more appropriate solution.

Additional code is implemented which accounts for delay present on signals not directly measuring the heart beat (e.g. The operation of a peak detector can be illustrated using a simple diode and capacitor, as shown in figure 22.
More important, this peak detector can operate at frequencies much higher than those for which there are adcs, since its only semiconductors are the op amps and diode, both of which are available into the tens of ghz.
One of the methods using op amp is given in the follwoing link. .sine wave, then there is an alternative using two peak detectors which produces the same results as ac coupling but without this problem but i doubt you need it. The input is v1 and the output is taken from node o. So instead of using only simple components to build a peak detector circuit, we also add buffers to the circuit. This enables us to figure 2. A peak detector is a series connection of a diode and a capacitor outputting a dc voltage equal to the peak value of the applied ac signal. Just above the capacitor in the middle, there is the black line is the output waveform which is tracing the peaks of input waveform (blue sine wave). When the input waveform falls below the dc peak stored on the capacitor, the diode is reverse biased, blocking current flow from capacitor back to the source. Up until the 1990s all digital magnetic recording devices used peak detectors to convert the playback waveform to bits. The ubiquitous ua741 was released in 1968 and is considered … The second op amp is a buffer. Basically, triangular wave is generated by alternatively charging and discharging a capacitor with a constant current. As i said before i need a peak detector with a working frequency up to 1 mhz.the maximum frequency of the circuit which shaikhsarfraz mentioned is 150 khz.
