The invention relates to the field of modulation and demodulation circuits, such as envelope detectors used to demodulate amplitude- modulated (AM) signals and amplitude-shift-keying (ASK) signals. By judiciously coupling an analog circuit comprising one resistor and two capacitors which are judiciously dimensioned to a port of a digital component, an extremely compact envelope detector can be obtained, which achieves demodulation of a binary ASK signal for direct coupling into a digital input port. Accordingly, a very compact envelope detector may advantageously be used in the data receiving part of a sealed device requiring postmanufactuπng data transfer, in combination with additional components that provide electromagnetic coupling, such as inductive coupling, capacitive coupling, or radiative coupling. An example of such a device is a credit card sized authentication token, the electrical personalization of which happens after the production of the card-like housing. | ||||||
