According to one embodiment of the present invention, a microwave or millimeter wave module includes a dielectric layer having a pocket formed substantially through the dielectric layer. The dielectric is attached to a metal substrate. The pocket has substantially vertical sidewalls. An integrated circuit is disposed in the pocket. Opposing sides of the integrated circuit are substantially parallel to the sidewalls of the pocket. An interconnect electrically couples the integrated circuit to a bond pad disposed on the outer surface of the dielectric layer. The interconnect has a length that is minimized to result in reduced inductance of the semiconductor device.

A design structure embodied in a machine readable medium used in a design process can include apparatus of a semiconductor chip operable to detect an increase in resistance of a monitored element of the semiconductor chip. The design structure can include, for example, a resistive voltage divider circuit operable to output a plurality of reference voltages having different values. A plurality of comparators in the semiconductor chip may be coupled to receive the reference voltages and a monitored voltage representative of a resistance of the monitored element. Each of the comparators may produce an output indicating whether the monitored voltage exceeds the reference voltages, so that the resistance value of the monitored element may be precisely determined.

A method of varying the gain of an amplifier and an amplifier array are provided. The amplifier array includes two or more amplifier stages (201, 202) connected in parallel with each amplifier stage having a gain control means. Input signal means (203, 204) are provided for each amplifier stage with the input signals of the amplifier stages being of different amplitude. Means for enabling and disabling an amplifier stage (216) are provided and means for summing the outputs of the enabled amplifier stages obtain an output signal (212). The gain of the amplifier array has a range from a low gain setting with a first amplifier stage (202) enabled, through increasing gain settings as the gain of the first amplifier stage is increased from a minimum to a maximum gain, a second amplifier stage (201) can then be enabled in addition to the first amplifier stage and the gain of the second amplifier stage increased from a minimum to a maximum gain, further amplifier stages are enabled as available up to a maximum gain setting for the amplifier array. Each amplifier stage that is enabled has a decreasingly attenuated input signal and a final amplifier stage to be enabled has a full input signal (203).
