Abstract

See full text

A tamper detection arrangement for use within an integrated circuit (1), the arrangement comprising: at least one input capacitor (4) having a first capacitance value; a feedback capacitor (5) having a second capacitance value; a sensing arrangement comprising an amplifier circuit having the at least one input capacitor as an input and the at least one feedback capacitor in a feedback loop across the amplifier operable to detect a change in the capacitance values between the at least one input capacitor and the feedback capacitor; and a protective shield to protect a sensitive area (2) of the integrated circuit from tampering, the shield being provided by the at least one input capacitor (4).
