  • Device for comparing the peak value of at least one voltage signal with a reference voltage
    Patent number: 7759983
    Abstract: A device for comparing the peak value of a periodic voltage signal or a linear combination of periodic voltage signals with a reference voltage includes a reference transconductor element for converting the reference voltage into a reference current, respective transconductor elements for converting each of the periodic voltage signals into respective periodic current signals, a current-comparison node for comparing the respective periodic current signals with the reference current, generating a comparison current as a difference between the sum of the aforesaid periodic current signals and the reference current, a current rectifier supplied with the comparison current, a hold capacitor charged with the output current of the current rectifier, and a discharge-current generator in parallel to the hold capacitor.
