  • Method for determining switching state of a transistor-based switching device
    Patent number: 7248084
    Abstract: A method, which is for determining switching state of a transistor-based switching device that includes a set of transistors, includes the steps of: applying a bias voltage to a transistor having a fastest response so as to dispose the transistors in the set in a desired transistor state; detecting a voltage level at a transistor having a slowest response to the bias voltage; and comparing the detected voltage level with a predetermined threshold voltage level in order to determine the switching state of the switching device. A transistor-based switching device is also disclosed.
    Type: Grant
