Patent ID: 7738565

Claim:
A method comprising: receiving an input signal; generating pulse edges based on the peaks of the input signal using a peak detection circuit, wherein generating pulse edges based on the peaks of the input signal comprises: splitting the input signal into a first input signal and a second input signal; delaying the second input signal with respect to the first input signal; comparing amplitudes of the first input signal and the delayed second input signal to produce an amplitude differential signal; and generating the pulse edges using the amplitude differential signal; and measuring the values of the peaks of the input signal using the generated pulse edges using a sampler circuit, wherein measuring the values of the peaks of the input signal using the generated pulse edges comprises: aligning the pulse edges with the peaks of the input signal, wherein aligning the pulse edges with the peaks of the input signal comprises delaying the input signal; and triggering the sampling of the input signal by the pulse edges.
