The method for inspecting an integrated circuit comprising a plurality of sub-circuits includes the determination of the supply current into at least one of the sub-circuits. This supply current is determined, while the other sub-circuits are operational, by measuring the voltage over a segment of the supply line through which this supply current flows. This supply line contains no additional components to facilitate the measuring of the voltage.

Method and apparatus for inspecting and integrated circuit by measuring voltage on a signal line

An amplifier used in a tuner of video and/or audio equipment has to amplify the received input signal but should add as little as possible noise and distortion to the amplified signal. To improve the operation of the amplifier and includes tuner, the amplifier of the at least two gain stages and switches for short-circuiting a gain stage when it is not necessary for the overall gain value.
