Abstract :
The design of a high performance envelope detector is made in this work. Proposed circuit does not need the traditional compensation between keeping and tracking required in these circuits due to a system by what the signal peaks are held in two periods and combined to obtain the envelope of the signal. Simulation results are offered comparing both the conventional and the proposed envelope detector and it is shown the superior performance of this circuit obtaining for a signal at 10MHZ smaller ripple (<1%), faster settling (0.4mus) and using smaller silicon area
