Abstract: Provided herein are new methods for determining the quantity of related enzyme complex components present in biological samples. The target analytes residing in the same original sample are related as components of a single enzyme complex or multiple enzyme complexes and are analyzed by the same analytical technique from the same original sample which may be split, fractionated, or analyzed directly.

Abstract: An operational amplifier is trimmed electrically using non-volatile fuses. The non-volatile fuses may be programmed electrically without destroying any passivation layers or other devices on the electronic component. In the case of an integrated circuit analog component, the trimming may be performed either at the wafer level or at the packaging level. The trimming may be performed specifically to adjust the quiescent current or offset voltage of the operational amplifier.

Abstract: An analog electronic component, includes input and output pins, analog devices and non-volatile fuses. The analog devices are operative to perform analog signal processing on signals received via at least one input pin and to output processed signals on at least one output pin. The analog devices include adjustable elements. The non-volatile fuses are coupled to the adjustable processing elements and are electrically programmable via at least some of the input pins. Programming the non-volatile fuses adjusts the adjustable elements to alter characteristics of the analog signal processing.
