Latest Patents

Donald A Conrad holds a patent for a "Depletion/enhancement mode FET logic circuit." This invention discloses a field effect transistor logic circuit that combines enhancement and depletion mode field effect transistors. The design features a depletion mode input transistor connected between an input node and an intermediate node, with its gating electrode linked to a fixed potential such as ground. Additionally, a self-biased depletion mode field effect load transistor is connected between a positive potential and the same intermediate node, which also connects to the gating electrodes of one or more enhancement mode field effect transistors. The source electrodes of these enhancement mode transistors are connected to a fixed source of potential, while their drain electrodes provide open drain outputs to subsequent logic stages. This configuration allows for the formation of DOT logic configurations, with the potential swing at the open drain outputs being significantly less than the potential difference between the fixed positive and ground supply potentials. Donald A Conrad has 1 patent to his name.
