1. A complex circuit comprising:

  • at least one hundred transistors;

    a plurality of inputs;

    one or more transistor stacks included within the at least one hundred transistors, the one or more transistor stacks each including two or more transistors of a same type coupled in series, at least some of the transistor stacks being coupled to at least one of the inputs; and

    logic to apply a selected input vector to the plurality of inputs during a standby mode, the input vector being selected based on a configuration of the one or more transistor stacks in the complex circuit block, the input vector being selected to turn off a first number of transistors in the transistor stacks, the first number being within a selected percent of a maximum number of transistors in the transistor stacks that can be turned off by any vector applied at the plurality of inputs.
